i'm not able to reproduce.  it's possible it graphics card related.  which GPU do you have and which driver version?  also, check the manufacturer's website to see if there are any updates for your particular card.  thanks...
*This happens with/without HWA(Firefox and Flash),
*This happens with/without OOPP.

I don't believe an in-product change will be needed for this since it's directly related to the release of Flash Player 11.3.300.257 and reproduces with older versions of Firefox. Given that, no reason to track for Firefox's next release. This still appears to be a significant Flash issue, however.

As you can see from the attachment, the issue is reproducing using Flash 11.3.300.250 and also my video card is a Nvidia GeForce 210 driver version 296.10.

I didn't noticed this behavior on Win 7 x86 with exactly the same configuration.

This is not a bug. The screen shot is correct result.
I'm unable to reproduce the underworld issue on Firefox 14b6 with Flash Player 11.3.300.257 on a Lenovo W500.  Flash Player 11.3 does widen GPU acceleration support to more older cards.

Disabling Hardware Acceleration through Flash Player Settings Manager is a quick and easy check to eliminate GPU as a root-cause.

There's a full troubleshooting guide here: 
http://helpx.adobe.com/flash-player/kb/video-playback-issues.html

If these issues persist, we're more than happy to investigate.  There's a much larger array of GPU and driver combinations in the field than we can hope to test, although we do our best to put a dent in that text matrix.

The best way to get a resolution for a particular display card is to file a bug against flash player at http://bugbase.adobe.com.  Including a URL to reproduce the issue and the output of dxdiag would be particularly helpful.

I've filed a bug on our end (3212149) to ensure that someone follows up on the information reported in this thread.  Any additional feedback, especially on results of the troubleshooting guide referenced above would be appreciated.

Even after several different searches in your bugbase I can't find an entry with that ID, and the dain bramaged decision to forego links for some lookalike onclick handlers that prevent one from opening results in new tabs certainly doesn't help.

Has that "bug on your end" been deleted?

Confirmed. https://bugbase.adobe.com/index.cfm?event=bug&id=3212149 leads to "The information requested is not found"
I filed the bug directly with the engineering team.  It's open and being worked on.

Also, I did paste the wrong bug number.  The internal bug ID is 3212446.

I'm more than happy to clone the internal engineering bug to a public bug if you'd like.  We would update that bug once the bug is closed on our end; however, it won't effect a fix any faster.
I can still reproduce  with Flash    Version: 11.3.300.262.

Dan Q, this bug is specifically about a regression in Flash 11.3. Unless you believe that the Java issue you're reporting was also caused by Flash 11.3, please file it separately and don't pollute this bug. If you do think that the Java regression was caused by Flash 11.3, please indicate why you think this (did you go back and test with Flash 11.2?).

    
    

    
  
Benjamin Smedberg et al, a new bug was filed with these symptoms paraphrased for Java - see #770398.

Could this be a DirectX 10.1 [HD 4xxx PCIe / GT(X) 2xx PCIe] only problem?
I saw only users with these cards having the problem.
I will test it with my HD 4670 AGP later.

This is D2D specific as well. GDI doesn't exhibit the problem.

    
    

    
  
Disabling protected mode in Flash configuration as described in the following page fixed this issue for me:
http://www.pcrx.com/resource_center/how-do-fix-flash-crashes-in-firefox-13.html

According to Adobe, this mode was introduced for Firefox users:
http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html

So who then should be blamed for this issue?

Army of Awesome shows people dumping Firefox in droves over this problem, somebody better fix it soon!

    
    

    
  
I can reproduce this on an ATI HD6970, running Windows 7 and Firefox 14.0.1. And Flash player 11.3.300.265. (Firefox is running in Hardware Accelerated mode with Direct3D 10 layers and Direct2D turned on).

This reproduces for me whether Flash GPU acceleration is turned on or off.

    
    

    
  
I can also reproduce this on an HD5850. To be honest I can hardly imagine the severity being sufficient to cause people to 'dump firefox in droves', but I will still see if I can get any debug info on the issue.

Umm, YouTube?

    
    

    
  
Hrm, there's not a lot that can be done here on our side I believe considering the structure of the sandbox. It appears on a scroll the sandboxed child window processes a WM_PAINT and WM_NCPAINT that our own plugin window has as well.

But then it also seems to get an WM_ERASEBKGND after that whose source is not clear to me. Additional invalidation that causes the area to be properly repainted seems to be purely coming from something internal as there are no Window messages sent.

The bottom line is I don't think there's anything we can do here and this is either a Windows or a Flash bug (or a combination of both).

The fundamental purpose of Youtube is watching videos. That activity does not seem to be severely affected.

The 'worst-case' scenario I can generate is pick a 4:3 pillarboxed video and pause it, then use scrolling to cause artifacts in the pillars for as long as the video is paused. But that disappear instantly when playing is resumed. That is hardly a critical interference with the user experience on YouTube.

I could see some other applications suffer a little more that regularly only invalidate a small area I suppose. But in reality I doubt there's a lot of users severely affected there either.

Most YouTube videos are 4:3. And the top portion of the bars do not re-black-themselves-out when the video is replayed, they still contain the distortion they acquired (or will acquire when scrolling down the page again).

Firefox should work on popular Web sites like YouTube.com out of the box.
Everyday people shouldn't have to deal with hardware acceleration in Preferences, downgrade to an older (insecure?) version of Flash using a special uninstaller, or change something in their video card settings to get YouTube.com to work properly. That's why the Twitter feed contains with messages like "Firefox doesn't work with Flash! I'm switching back to IE/Chrome."

I can't believe any person would claim YouTube.com is too trivial to warrant fixing a serious and embarrassing bug. Getting YouTube.com to work properly should be our top and quick priority right now.

The video is still playing. And is perfectly watchable, i.e. the activity of watching a video is not severely affected.

Then again, we can't fix a bug that we didn't introduce. If you read the history of this bug you would notice several people have spent time on this bug, and all of them have come to the same conclusion, it's most likely not a bug in firefox, it's a bug in Flash. Simply from the fact that it isn't in old flash versions with new firefox versions, but it is in new flash versions with older firefox versions. Adobe has also commented on this bug and said they are working on it, so the bug is most certainly not being ignored, and we'll provide any assistance required, however to the best of my knowledge at this point they've not asked for any.

Nobody says the bug shouldn't be fixed. My statements were two-fold:

1. At this point it looks like we can't fix this bug.
2. Although the bug is obviously there, and should be fixed, I doubt it's bad enough to cause people to 'dump firefox in droves'

In any case, let's try and keep the bug focused on any information that might help Adobe find the bug (or help them find out if the update in Flash is simply exposing a bug in firefox that was already there, so we can fix it). At this point as best I can tell the flash sandbox 'window' is completely controlled by them and there is absolutely nothing we can do about this bug, except maybe a hack which generates bogus repaint events but that seems like a very bad approach and might cause all kinds of other performance issues.

    
    

    
  
If it was our bug, or it was a Flash bug that we can work around, we'd definitely fix it. But it's a Flash bug with no indication that we can work around it, other than perhaps by forcing the sandboxed mode to be turned off.

We are deeply concerned about this bug and other Flash 11.3 bugs:
https://groups.google.com/d/msg/mozilla.dev.planning/RwpipKzSVBg/XBkuTADEjyoJ

    
    

    
  
As I understand the technical commentary here, this bug only affects windowed-mode Flash. Is that correct?

Note that we are tracking at least one other Flash-related painting issue, bug 775724, which is windowless-mode only, but right now the regression range and whether this is a FF or Flash regression is unclear.

    
    

    
  
So, I think this might be related to bug 587508 (which I still suspect may be a bug in the windowing system). We added a work-around problem in windows/nsWindow.cpp:6836.

However the invalidate that is sent there might not cause a proper redraw in the Flash player when it is in 'sandboxed' mode.

    
    

    
  


  
I've found a work-around for the problem which I believe to be viable and safe.

Handle ChildWindowFromPoint returning NULL as well.

I suggest
  while (current) {
    HWND next = ::ChildWindowFromPoint(current, p);
    if (next == current)
      break;
    current = next;
  }

We're going to invalidate the wrong rect here if the child happens to have its top-left not at 0,0. I suggest checking for that in the loop above and only doing this hack for windows that are at 0,0.

    
    

    
  


  
I updated the patch and made it more correct. I think I've still seen very subtle artifacts on some very rare occasions but it seems to fix practically all occurrences.

Will this workaround be removed from Firefox when a "true" fix will be added to Flash by Adobe?

    
    

    
  
Is this workaround limited to Flash plugins or does it affect all plugins? I'd like to land this up the trains as fast as possible, but I'd like to understand the risk a little better.

This work-around will affect all plugins - however all it does is invalidate additional surface area. In theory the worst-case scenario is a small bit of content getting needlessly redrawn. This might affect performance, but not correctness.

So it will fix bug 770398 (the Java equivalent of this bug) too?

Maybe more votes for the issue will force Adobe to fix this issue on their side:

This Adobe bug number (3212386) doesn't fit with this one in the title of the current bug (3212446). Is yours correct?

I can't find an entry to the issue with ID 3212446. I get "The information requested is not found" error: 
https://bugbase.adobe.com/index.cfm?event=bug&id=3212446

Adobe's bugbase Issue 3212386 ("Image Corruption when scrolling with embedded youtubes and some other flash content") I tracked from the comment #32 that links to Adobe issue 3228655, where the reference to that specific issue 3212386 was given.

I see that bug directly linked to what is discussed here. Do you think it's different issue?

    
    

    
  
In the 3228655 issue you find 4 bugs/problems. In that, the 3rd problem is the scrolling problem (yeah something like this: http://i.imgur.com/YKKZY.jpg). But it fixed after I do this 4 steps: http://www.pcrx.com/resource_center/how-do-fix-flash-crashes-in-firefox-13.html and now work normally. I linked these topics, because maybe it has something connection in it's problems.

And I wrote first to the adobe, than they linked this topic first. If they don't linked this topic, I don't know about it.

    
    

    
  
Well, Adobe didn't fixed the scrolling issue. You have to manually disable Firefox protected mode (introduced in Flash Player v11.3.300.257) as a workaround. Instead, Adobe created an issue 3212386 where it is said that they would not fix it in the next release and it might require more votes to rise it's priority. It is good that Firefox developers will add a workaround as well, but actually it's the Adobe's bug that Adobe must fix.

If you are continuing to experience issues, please file a new bug over at http://bugbase.adobe.com/ with a clear description of the problem and steps to reproduce.  We'll be happy to investigate.

Also, please understand that by disabling ProtectedMode, you've permanently disabled modern security protections on your system for all future Flash Player versions.

A better workaround, if you don't need Flash Player 11.x features, is to roll back to Flash Player 10.3.  We maintain this version with current security patches for enterprise customers.

You can find the latest Flash Player 10.3 version here:

Workaround for an invalidation problem with flash v2

[Triage Comment]
Helps with new repainting issues in Flash 11.3. My only concern here is that plugin regressions may get lost in the noise of Flash feedback, but the number of reports of this bug specifically is worth the low risk of regression.

    I understand there was some concern over performance for this fix?    Fwiw, we can only reproduce this bug when HW accel is enabled in FF, not when its disabled.

And only then will we use this workaround.

Is this the problem where images of youtube controls or comments can appear to the side of 4:3 videos or is that another bug?

Yes, and sometimes the controls are cut in half.

The bug seems to have returned with recent 15 (beta) updates.

True of Flash 11.3.300.268 and the latest update 11.3.300.271
So it must be a Firefox problem.
Using Firefox 15 Beta, Windows 7 Ultimate 64-bit, GPU is NVIDIA GT 220.

    
    

    
  
Its not fixed in the latest nightly either, not sure if was meant to be?

    
    

    
  
I filed a new Bug 783801 with Flash 11.3.300.271

    
    

    
  
I'm willing to bet this is an issue with NVIDIA drivers. Everyone here with the problem has NVIDIA cards. Also, we all seem to have forgotten about Bug 770398...

    
    

    
  
Fwiw, this work-around is pretty fiddly. If they change their window layout it might need a little nudging.

NOTE: This is not the Slackware 64-bit package, it was the beta track downloaded off the Mozilla FTP site and updating from there. Slackware uses the stable track which I do not have installed.

    
    

    
  
Dan Q, this issue was specific to Flash 11.3 on Windows. Please file a new bug for your specific issue.

Forgot to mention that there were no problems in this build. Maybe thats why you thought it was a bug :)
