User Agent: Opera/9.80 (Macintosh; Intel Mac OS X 10.6.8; U; en) Presto/2.9.168 Version/11.51 Steps to reproduce: 1. Built NetscapeCoreAnimationPlugin provided by webkit community 2. Placed the plug-in "~/Library/Internet Plug-Ins" 3. Opened the test page provided with the plug-in. NetscapeCoreAnimationPlugin can be checked out from: http://svn.webkit.org/repository/webkit/trunk/Examples/NetscapeCoreAnimationPlugin Actual results: Plug-in was displayed but the animation wasn't rendered. It displayed a single frame. Everything else seems to be working fine. The plug-in was detecting mouse clicks but the rendering had frozen. Expected results: It should have rendered the animation.

You need to add the following lines to the top of NetscapeCoreAnimationPlugin's main.m for it to be able to compile (at least on OS X 10.6.8): typedef int16_t int16 typedef int32_t int32 By default NetscapeCoreAnimationPlugin compiles as a 32-bit binary (not a 64-bit binary). But this bug happens whether or not this plugin runs as a 32-bit binary or a 64-bit binary. It only happens when the plugin is run out of process (when the browser runs in 64-bit mode). The bug doesn't happen when the browser runs in 32-bit mode (when the plugin runs in process). Here's the regression range: firefox-2011-07-13-03-07-41-mozilla-central firefox-2011-07-14-03-07-48-mozilla-central It's not obvious (at least to me) which patch in this range could have triggered the bug, so I'm going to do an hg bisect to find out. By the way, this bug also effects the QuickTime plugin, so it's quite a bit more important than it might appear to be on the surface.

This is intended behavior. This example plugin does not use the proper drawing model for gecko. The only difference is that Gecko expects an InvalidateRect event to be notified that the plugin needs to be repainted: https://wiki.mozilla.org/NPAPI:InvalidatingCoreAnimation

Benoit, how would you revise the NetscapeCoreAnimationPlugin to fix this problem? Someone should open a WebKit bug on this.
Finally, if this problem isn't fixed soon in the QuickTime plugin, we'll need to include some kind of QuickTime-specific workaround (to allow it to continue to use "improper" methods).

Josh, do you have any contacts in Apple you can talk to about this bug? If not, maybe we should just bring it up on the plugin-futures mailing list.
Benoit, when was Core Animation support "turned on"? Do you know which patch triggered this bug? I don't see anything Core-Animation-specific (or even Mac-specific) among the patches landed during the regression range.

I wasn't looking carefully enough at the mozilla-inbound merges. Here's the patch that turned on Core Animation: Bug 663259 - Enable Mac Async plugin by default. r=cjones,mattwoodrow author Benoit Girard <b56girard@gmail.com> Tue Jul 12 10:31:18 2011 -0400 (at Tue Jul 12 10:31:18 2011 -0400) changeset 72713 5cea57e451dd parent 72712 2d5bc18fdf9c child 72714 ce95693001bc pushlog: 5cea57e451dd
Ohh I never noticed that Quicktime was affected by this. We should be able to land a patch to refresh at 60 FPS, however our hope was to remove support for vanilla CoreAnimation without the CoreAnimationInvalidate extension we proposed in 2010. Contacting Apple to fix Quicktime for this would be ideal.
Benoit, in bug 663259 comment #39 you talk about "special casing", with the possible implication that the QuickTime plugin behaves differently when it thinks it's running in a Firefox release. Is this what you meant? If so, do you know what the QuickTime plugin does differently? Does it possibly fall back to not using Core Animation? By the way, I tried to fool QuickTime into thinking it was running in a Firefox release by changing a current nightly's user agent string to match that of FF 7.0.1. This had no discernable effect on QuickTime's behavior -- this bug still happened. (By the way, I've been testing with movie trailers at http://www.apple.com/trailers, particularly http://trailers.apple.com/trailers/independent/beingelmo/. Note that, because of bug 687610 and bug 670036, you need to clear the network cache before running every test.)

We do have significant changes with the async changes so we should be careful in assuming that this will work on the release version without good proof. (In reply to Steven Michaud from comment #10) > Maybe we could do this as a QuickTime-specific "quirk". A quirk would probably be the best way, I want to limit the number of plugins that depend on a invalidate timer. If plugins don't want to care about invalidation they can setup their own refresh timer at whatever rate they care about.

If this is the quirk we need for quicktime we should make it a click-to-play plugin: the timer solution is absoutely terrible for power usage/battery life, especially after you've reached the "end" of a movie and there are no more actual changes being made.
Is there a way to only use the timer when we "need" it (while a movie is playing)?
Actually, it might be easiest just to refuse to use Core Animation with the QuickTime plugin (and make this the quirk). We could (presumably) fall back to using Core Graphics.
Additional note: Plugins using CAOpenGLLayer and CVDisplay Link to update the layer is also failing on FF8. The same works fine with FF7, FF6 and webkit based browsers. Should the plugin raise InvalidateRect event even while using CVDisplay Link to update ? OR Is this a bug with FF8 ?
Nominating for tracking as I was contacted by Sling Media - they indicated that this affects their product and they believe it will affect many others as well.

> Would this be a simple pref flip? Or is the blacklist in code? I was thinking we could add a QuickTime-specific quirk to do this. But a quirk (or quirks) would only work with QuickTime, or with a very short list of majorly popular plugins. Plugin vendors need to be made aware that this is a problem that should be fixed on their end, as per comment #2.

If we do it only for OOPP only then we have to change this from true to false: http://mxr.mozilla.org/mozilla-central/source/dom/plugins/ipc/PluginInstanceChild.cpp#417
I thought we removed all mention of the non-invalidating CoreAnimation support because we got Flash to support the invalidating one in the FF4 timeframe. Why can't we remove it from both the in-process and out-of-process impls?
> Plugin vendors need to be made aware that this is a problem that > should be fixed on their end, as per comment #2. However, we could probably have done a better job of announcing the change that triggered this bug, and how to work around it. Maybe we should consider whitelisting plugins that we know can do Core Animation properly (by our lights), and falling back to something else (Core Graphics?) for every plugin not on the whitelist.
Which plugins are those? QuickTime doesn't use invalidting CA, right, so we wouldn't want to whitelist it?

Has a bug already been open for Webkit? If so what is the #? (In reply to Steven Michaud from comment #3) > Benoit, how would you revise the NetscapeCoreAnimationPlugin to fix this > problem? > > Someone should open a WebKit bug on this.
> Maybe we should consider whitelisting plugins that we know can do > Core Animation properly (by our lights), and falling back to > something else (Core Graphics?) for every plugin not on the > whitelist. I just realized that using a whitelist has a severe drawback -- if your plugin isn't on the list, how will you test implementing "correct" support for Invalidating Core Animation? So we probably can't use a whitelist. How about if we only support Core Animation (of any kind) for those plugins that explicitly request support for Invalidating Core Animation?
I think whitelist-ing for CoreAnimation would be perfectly acceptable. This would mean that other plugins would have to use InvalidatingCoreAnimation which is our supported drawing model. We should start to deprecate CoreAnimation drawing model since we don't want to support this going forward.
Whitelisting for plugins that explicitly request *Core Animation* would be alright. Whitelisting for plugins that explicitly request *Invalidating Core Animation* wouldn't be -- for the reason I gave in comment #26.
Actually since we want Quicktime to default to Core Graphics (or preferably ICA) then there is no reason to whitelist plugins to use CoreAnimation. I filed a new bug 693727 to investigate removing the drawing model completely.
The problem with adding a quirk to make QuickTime use Core Graphics is: What do we do about the other plugins whose vendors are only now learning that they need to use Invalidating Core Animation with the next Firefox release (and not the non-invalidating Core Animation that they were expecting to be able to use).
Let's continue that discussion in bug 693727. I'm open to having a deprecation plan if required.
The discussion is also directly relevant here. We need to choose among the following ways to fix this bug (or something like them): 1) Add a quirk to force QuickTime to use Core Graphics, because it can't do Invalidating Core Animation. 2) Force all plugins that explicitly request Core Animation (but not Invalidating Core Animation) to use Core Graphics. 3) Force some plugins (like QuickTime) that explicitly request Core Animation to use Core Graphics. This would be something like a blacklist. In this I assume that we can't support non-invalidating Core Animation, because of the performance penalty. The alternatives would change if we found ways to alleviate the performance penalty.
All these 3 solutions all have in common that we force quicktime to use Core Graphics. We need to make sure that it will correctly use Core Graphics when Core Animation is not available. I'm waiting for my try build to finish to confirm this.
> We need to make sure that it (QuickTime) will correctly use Core > Graphics when Core Animation is not available. Yes indeed. I've assumed that QuickTime used Core Graphics before your patch for bug 663259 landed (which turned on Core Animation, or at least made it the default). Is this true?
(In reply to Steven Michaud from comment #34) > I've assumed that QuickTime used Core Graphics before your patch for > bug 663259 landed (which turned on Core Animation, or at least made it > the default). Is this true? I think it might of used QuickDraw.
> I think it might of used QuickDraw. I vaguely remember something about QuickDraw not working in OOPP plugins. Josh?
QuickDraw was never supported for OOPP because the drawing model was not designed to be remoted easily. This was the reason we had to white-list plugins we would allow to run in 32-bit OOP mode to Flash+Java since in 32-bit mode it is perfectly valid to not request a drawing model and expect Quickdraw.
Thanks for the info. Note that even before Core Animation was turned on/made the default, using QuickTime didn't force a restart in 32-bit mode. I'm going to write a test patch that logs which drawing modes plugins claim to support, and which drawing mode we end up using.
So even the current version of Quicktime doesn't support ICA or CG. With my patch we detect that Quicktime request a proper drawing models and we get the dialog to restart in 32-bit mode. We should request Quicktime to support ICA. In the mean time our options are to either fix the timers to work correctly or to require the 32-bit restart. I think the first is the best user experience.
I tested with my logging patch, backported to the patch just before the patch for bug 663259 landed (the one that broke our support for CoreAnimation, as opposed to Invalidating CoreAnimation). This shows that QuickTime used CoreAnimation with Firefox even before that patch landed -- not CoreGraphics, and not QuickDraw. Sorry for the confusion :-( And I've confirmed what Benoit says: If you stop the QuickTime plugin from using CoreAnimation it falls back to using QuickDraw. Something we want to avoid, if at all possible. I also discovered that this bug goes away if you change plugins.use_layers from its (post bug 663259) default value of true to false. Is this a viable solution? Could we do this for all plugins that request CoreAnimation (as opposed to Invalidating CoreAnimation)? Do we need the timer if plugins.use_layers is false? (Note that, because of bug 687610, you need to clear your network cache before testing QuickTime media.)
With my logging patch I've found out that Flash explicitly requests (and uses) Invalidating CoreAnimation. So we wouldn't need to turn off plugins.use_layers for Flash.
By the way, here's my logging patch. A tryserver build should be available by (I hope) the end of the day.
I think Firefox should support both CoreAnimation and Invalidating CoreAnimation plug-in for some more time. This would provide time for the plug-in makers to make changes on their end.
Benoit, please answer my questions from comment #40.
Sorry Steven, I've been traveling.

It would be possible to do that but I feel like it's not the right solution. Presumably the invalidate events are not working. I can take a look tomorrow.

Presumably the invalidate events are not working. I can > take a look tomorrow. Thanks. Maybe we could fall back to my solution (turning off plugins.use_layers for plugins that request CoreAnimation, but not Invalidating CoreAnimation) if we can't find a better one in time. It does have the advantage of being simple. And time is a problem. I really think we should get this fixed in FF 8.
FYI if there isn't a resolution here we will probably back out bug 663259. Please let me know if there are large issues with doing so.
I had a bit of time to look at it before the next lecture. With Pre-async plug-in the browser would drive the invalidate/redrawing so I built the invalidate timer in the parent process to save some IPCs call. With async plug-in the invalidate event has to start from the plugin process. The CA Timer quirk doesn't do this. I'll write a patch for this tomorrow. We should still prepare a deprecation plan for CA in bug 693727.

Comment on attachment 567136 [details] [diff] [review] TimerFix Benoit, please tell us more about this patch. It looks like you've moved the timer from the browser process to the plugin process, and turn it on only for plugins that use CoreAnimation (though not Invalidating CoreAnimation). What are the consequences of this? I expect there will be less of a performance hit running the timer in the plugin process, but have you tried to measure how much? It looks like we were already using the browser process timer for CoreAnimation plugins (aside from Flash). Then why did we have this bug? You haven't made any attempt to make the timer only run when plugin media is playing. Is it because this would be too difficult? Is it because you don't think it's necessary? I haven't yet tested this patch, but I will in the next hour or so.
(In reply to Steven Michaud from comment #43) > Here's a tryserver build of my logging patch: > http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/smichaud@pobox.com- > 6859ddd1b171/try-macosx64/firefox-10.0a1.en-US.mac.dmg I tried this build, with the webkit sample plugin (http://svn.webkit.org/repository/webkit/trunk/Examples/NetscapeCoreAnimationPlugin), the animation renders fine (with plugins.use_layers set to false). My plugin uses CAOpenGLLayer and Core Video Display Link to update the layer. Browser fails to render Animations (older versions of FF (v4, v5, v6) and Webkit browsers work fine). I used QCCompositionLayer in my plugin just to test. It renders the animation fine. CAOpenGLLayer and Core Video Display Link fail to render. Any ideas on this ?
I explained the problem in Comment 49.

InvalidatingCoreAnimation solves this, thus we should do outreach to get Quicktime to support ICA.
(In reply to comment #53) My patch from comment #42 is a logging patch, for debugging purposes. As I already said, it *isn't* a fix, and doesn't change current behavior. > I tried this build, with the webkit sample plugin > (http://svn.webkit.org/repository/webkit/trunk/Examples/NetscapeCoreAnimationPlugin), > the animation renders fine (with plugins.use_layers set to false). So setting plugins.use_layers to false makes the NetscapeCoreAnimationPlugin example work correctly in current versions of Firefox. This confirms my own results.

Is all this with plugins.use_layers set to 'false', or with it left at its default value of 'true'?
(In reply to comment #54) Thanks for the info. But you didn't answer one of my questions. >> It looks like we were already using the browser process timer for >> CoreAnimation plugins (aside from Flash). Then why did we have >> this bug? > > We are only using the process timer for plugins that don't support > InvalidatingCoreAnimation which the only plugins I'm aware of is > Quicktime. Then why does QuickTime have this bug in current code?
I've now talked to Benoit on IRC, and have a better understanding of this bug ... or so I hope. Benoit, please tell me if there's something wrong with any of the following: 1) The timer in the browser process hasn't worked properly since we started drawing plugins asynchronously (since the patch for bug 663259 landed). This is why it didn't help with QuickTime. 2) Asynchronous plugin drawing is turned on by setting plugins.use_layers to 'true', and turned off by setting it to 'false'. 3) Using a 50 fps timer with asynchronous plugin drawing doesn't increase the number of IPC calls, and so should have no effect on performance. Given all this (and assuming I haven't misunderstood), is it worthwhile only using the timer (in the plugin process) if plugins.use_layers is 'true' (and if layers.acceleration is also turned on)?
Comment on attachment 567136 [details] [diff] [review] TimerFix I can't see anything wrong with this patch, but I think you should consider my suggestion from comment #57 (that you ensure the plugin-side timer is only used when layers.acceleration is turned on and plugins.use_layers is true). I tested on both OS X 10.6.8 and 10.7.2. I had no problems on 10.6.8. And though I did have a significant problem on 10.7.2, it was only with the NetscapeCoreAnimationPlugin example, and not with QuickTime. This patch may need revision. But I think we should land it as is, as quickly as possible, so that interested plugin vendors can test with it. Shiv and srichard@slingmedia.com, this particularly means you :-) But we'd also like to get tests of any other plugins that support CoreAnimation. My problem on 10.7.2 was heavy flickering with the NetscapeCoreAnimationPlugin example. I've no idea why I only saw this on Lion. The problem went away when I turned plugins.use_layers off. I did some performance testing, but it was a comparison of apples and oranges -- of a completely unoptimized patched build with an optimized nightly. Even this test showed only a moderate performance penalty. But I need to retest with an optimized build of the patch. Once again, note that, because of bug 687610, you need to clear your network cache before each test of QuickTime media.
Attachment #567136 - Flags: review?(smichaud) → review+
Here are the results of my (very limited) performance tests: I tested with a single QuickTime video (http://trailers.apple.com/trailers/independent/beingelmo/) on both OS X 10.6.8 and 10.7.2. I compared performance with the patch to performance without the patch (in equivalent nightly code) with plugins.use_layers turned off. On 10.6.8 I saw a 10%-15% performance loss in the plugin-container process, and about a 10% gain in the firefox-bin process. On 10.7.2 I also saw the ~10% gain in the firefox-bin process, but I don't think I saw any performance loss in the plugin-container process. This puzzles me. It may simply have been because the CPU usage jumped up and down a lot more on 10.7.2 (both with and without the patch). I measured performance running top after sshing in from another machine.
I should mention that I tested on a very fast machine -- a few months old MacBook Pro. The performance penalty of the patch in the plugin process would probably be higher on an old, slow machine.

(In reply to Ehsan Akhgari [:ehsan] from comment #66) > https://hg.mozilla.org/mozilla-central/rev/3c5e89543399 I see three issues in this 1. In a plug-in using a Layer derived from CAOpenGLLayer and using OpenGL textures for drawing, I see constant flicker. One frame is drawn and after that I see a white patch. No error messages are printed in the console.app 2. In case of NetscapeCoreAnimationPlugin the animation rendering is slower on the build compared to Safari and Google Chrome. 3. The browser no longer respects "asynchronous" property of CAOpenGLLayer. Irrespective of whether "asynchronous" is set to "YES" or "NO", the "drawInCGLContext:" and "canDrawInCGLContext:" callbacks occur. "canDrawInCGLContext:" should be called only when asynchronous is set to true/YES. So I will reopen the bug.

I have a few things in mind today that I will play with. Regarding #2 I don't think were concerned about the performance of CoreAnimation plugins. We're only concerned about plug-ins using the InvalidatingCoreAnimation model.

I have a build that fixes problem 1) building on try. I'm not sure why this only happens with certain plugins.

I was going through the timer patch. It looks to me that render performance(#2) can be improved by changing the FPS rate to 60. We need to consider this because current rendering is a little sluggish. This line of code #define DEFAULT_REFRESH_MS 20 // CoreAnimation: 50 FPS
Do you have any particular example of this in mind?

The results are mixed. On some macintosh machine the build is working fine and in some others the plug-in is not rendering. I tested it with this plug-in http://www.box.net/shared/6oemiidlxo2sh78qlzz0. I will attached the graphics card info of the Mac machines. Please let me know if you need any other clarifications.
I did some testing as well, we don't want to purse the build from Comment 77.

Comment on attachment 568138 [details] [diff] [review] Don't use async plugin for CoreAnimation (Non ICA) I tested the build made from this patch (from comment #89) on OS X 10.7.2. I had no problems. I tested with the NetscapeCoreAnimationPlugin and with http://trailers.apple.com/trailers/independent/beingelmo/ (QuickTime media). Note that, because of bug 687610 and bug 670036, you need to clear the network cache before running any QuickTime test.
Tested with build with a CAOpenGLLayer based plugin. Following is the result ============================================================ | OS | Graphics Card | Result | ============================================================ | 10.6 | ATI Radeon X1600 | Fail | | 10.7 | ATI Radeon HD 2600 Pro | Pass | | 10.6 | NVIDIA GeForce GT 330M | Pass | | 10.6 | NVIDIA GeForce 9400M | Fail | | 10.6 | ATI Radeon HD 2600 Pro | Fail | | 10.6 | Intel HD Graphics | Pass | ============================================================ Pass meaning plugin renders animation. Fails meaning No animation seen.
The ATI Radeon X1600 doesn't get layers acceleration so it should be unaffected with these changes. Are all of these working with Firefox 7.0?
Yes all these work with Firefox 7.0
Shiv, could you try to find which mozilla-central nightly (or nightlies) your problem(s) started with? Since you may have more than one problem, there may be more than one regression range. mozilla-central nightlies (and other kinds of nightlies) are available at ftp://ftp.mozilla.org/pub/firefox/nightly/.
Another thing, Shiv: In your tests please test with plugins.use_layers set to false.

Continuing from where shiv had left. I tested most of the build from October to July. The issue started with firefox-8.0a1 nightly build of July 14. The build is available at ftp://ftp.mozilla.org/pub/firefox/nightly/2011/07/2011-07-14-04-02-53-mozilla-inbound/firefox-8.0a1.en-US.mac.dmg I tested builds of July 13 to July 10. There were no issues with them. Hope this helps.
I tested this on machines having Intel HD Graphics card and NVIDIA GeForce 9400M. July 14th build failed to render on both the machines.

Sorry Benoit. I tested a wrong build. I will try your build again. Please ignore these statements.
I tested both the builds, Benoit : http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/b56girard@gmail.com-27349b705abd/try-macosx64/firefox-10.0a1.en-US.mac.dmg plugins.use_layers = true Steven Michaud : http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/smichaud@pobox.com-fbddaeff01fa/try-macosx64/firefox-10.0a1.en-US.mac.dmg plugins.use_layers = false Builds work fine on machine having Intel HD Graphics card but fails to render anything on machine having NVIDIA GeForce 9400M Graphics card.
Just to add to the issue. I used BasicMediaPlayer.plugin of FireBreath 1.6 on my machine having NVIDIA GeForce 9400M Graphics card. The nightly builds did not render anything. While on my other machine with Intel HD Graphics card there was a constant flicker, which is also seen on Firefox 8. BasicMediaPlayer.plugin of FireBreath 1.6 uses InvalidateRect event.

So apparently the patch for bug 671189 didn't trigger this problem. I'll come up with another guess, and prepare another tryserver build.
> So apparently the patch for bug 671189 didn't trigger this problem. > > I'll come up with another guess, and prepare another tryserver build. I'm still working on this. In the meantime, Vishvesh, could you test both of the following nightlies (with plugins.use_layers false)? Note that they are both mozilla-central nightlies (not mozilla-inbound nightlies). ftp://ftp.mozilla.org/pub/firefox/nightly/2011/07/2011-07-13-03-07-41-mozilla-central/firefox-8.0a1.en-US.mac.dmg ftp://ftp.mozilla.org/pub/firefox/nightly/2011/07/2011-07-14-03-07-48-mozilla-central/firefox-8.0a1.en-US.mac.dmg
Vishvesh: For completeness sake please also test this nightly (with plugins.use_layers set to false): ftp://ftp.mozilla.org/pub/firefox/nightly/2011/07/2011-07-15-14-04-43-mozilla-central/firefox-8.0a1.en-US.mac.dmg
And here are two more builds to test with, Vishvesh. Once again please test with plugins.use_layers set to false. They are built from mozilla-central code as of when a particular patch was landed, at different times on 2011-07-14. The one labeled 0141c3f5b18c corresponds to the patch for bug 670508. The one labeled a0ea3fd86f20 corresponds to the last of the patches for bug 684484. They aren't tryserver builds (the tryserver can't do builds like that). Instead they're custom builds that I made. Their symbols aren't stripped, and they have optimization turned off, but they aren't (technically) "debug builds". http://people.mozilla.com/~stmichaud/bmo/firefox-8.0a1.en-US.mac-0141c3f5b18c.dmg http://people.mozilla.com/~stmichaud/bmo/firefox-8.0a1.en-US.mac-a0ea3fd86f20.dmg

Need to test them on NVIDIA GeForce 9400M Graphics card.
Inbound is a branch where developers check their changes in. It is merged daily or so (not necessarily nightly like nightly builds) with mozilla-central once the changes have passed all automated tests. The branch should be treated as even less stable that mozilla-central. This makes it so that changes that fail automated tests wont make it to mozilla-central. Changes will typically hit inbound a day before central, however a developer can land directly to mozilla-central in which case the mozilla-inbound branch will get the change latter.
Thanks Girard.

I have got few questions 1. How long would it take to move these changes to trunk(FF8)? 2. What was the fix? 3. Is it needed to set "plugins.use_layers" to false before using Core animation based plugin?
Vishvesh, please test all five builds that I asked you to test, including those from comment #111 and comment #112. I'm only interested in tests on those machines where some tests didn't pass with plugins.use_layers set to false. I'm trying to find the patch that caused some problems not to be fixable by turning off plugins.use_layers. > 2. What was the fix? To make plugins.use_layers default to false.
The patch that fixed this bug (which made plugins.use_layers default to false) was landed at bug 663259. It turned off the changes that had earlier been made by the patch for bug 663259, without actually backing them out. However, you and Shiv have given us evidence that some problems started happening around the time that the patch that bug 663259 landed on the trunk (aka mozilla-central), which *can't* be fixed just by setting plugins.use_layers to false. And since the patch for bug 663259 wasn't backed out, maybe some part of it is causing your problems even when it's changes are (we think) turned off. Or maybe the cause is some other patch landed around the same time. That's why your tests are so important to us -- we want to find out what triggered these problems. (The patch for bug 663259 landed on mozilla-central on 2011-07-13, and appears in the 2011-07-14 and subsequent mozilla-central nightlies.)
> 1. How long would it take to move these changes to trunk(FF8)? The "backout" patch at bug 663259 (the one that (we hope) turns off the effects of the changes made by the original patch for that bug) has already landed on mozilla-central and the beta branch. That means it's present in current mozilla-central nightlies, and will be present in the next FF8 beta, and also in the FF8 release (when that happens). > 3. Is it needed to set "plugins.use_layers" to false before using > Core animation based plugin? My understanding is that setting plugins.use_layers to false makes us treat plugins that do Invalidating Core Animation exactly the same as those that do Core Animation. But that may not be right. Benoit?

I have tested the builds of comment 111 and 112. The report in comment 119 includes report for those build and they are working on the machine where it had failed previously. Last time when I had tested them plugins.use_layers was set to true.
Any updates on this Issue. Any idea on the release date of Firefox 8. Is it still going to be November 8?

Is this a clean fix or a temporary work around?
It's a clean fix for 8.0, 9.0 since the feature was turned off. It is temporary because the feature will be re-enabled once the problems are addressed.

I see this issue again on Firefox 9 beta build. In the build plugins.use_layers is set o false.
Any updates on this issue?
I just tested with Firefox 9 beta and Quicktime renders fine for me. Do you any additional info?
The problem is with plugins using CAOpenGLLayer. Rendering is fine on some machines but on some other machines animation is not seen. Following is the result ============================================================ | OS | Graphics Card | Result | ============================================================ | 10.6 | ATI Radeon X1600 | Fail | | 10.6 | NVIDIA GeForce GT 330M | Pass | | 10.6 | NVIDIA GeForce 9400M | Fail | | 10.6 | ATI Radeon HD 2600 Pro | Fail | | 10.6 | Intel HD Graphics | Pass | ============================================================ Pass meaning plugin renders animation. Fails meaning No animation seen.
Any updates on the issue?
I can reproduce the bug but only manually setting plugins.use_layers to be true. Can you try to reproduce the bug with a fresh profile? I suspect you have a preference that is interfering with the default configuration. I have tested on a: - AMD Radeon HD 6750M - ATI Radeon HD 5770
Can you please share the plug-in you had used for testing?
I created new user account and tried it again. I can still reproduce the issue. It would be good if you could share the plug-in you had used for testing.

There are some Intel graphics card on which the rendering doesn't happen. I can try to regenerate with your plug-in.
I've been using Quicktime. I'll get a hold of a NVIDIA machine to test.
I am not sure whether Quicktime uses CAOpenGLLayer. I am seeing this issues with plug-ins using CAOpenGLLayer for drawing.
(In reply to Benoit Girard (:BenWa) from comment #139) > I've been using Quicktime. I'll get a hold of a NVIDIA machine to test. I was debugging this issue, it looks like "-(BOOL)canDrawInCGLContext:(CGLContextObj)glContext ..." is not getting called on certain machines. Any idea on what could cause this issue.
I've just tried Quicktime on a X1600 and it work. This issue no longer applies to the current bug report. Can you open a new bug report with detailed STR, what plugins to use with which hardware and CC me?
okay
We are seeing the same bug in unity. Try installing the unity plugin, and going to http://unity3d.com/gallery/demos/live-demos to see the problem. In Firefox 10, when running in 64 bit mode, this shows very bad flicker.
