[Tracking Requested - why for this release]:

I can't reproduce it with my Nvidia GPU.

Comment 4

[Marcia Knous [:marcia]]

Tracking 53+ - we should find out if other Radeon GPUs are affected as well. ni on Andrei to see if SV has any such machines available to test.

Comment 5

[ignus]

Got some free time for some testing
1. Updated video drivers to latest version (16.12.1). Same result
2. I can reproduce this problem on every wabpage, not just google.com, except https://www.mozilla.org/ :)
3. With hardware acceleration disabled everything is fine to

Any suggestion?

Comment 6

[Milan Sreckovic [:milan] (needinfo for best results)]

Really surprising the change flagged in comment 0 would be responsible for this.  Is about:support drawn incorrectly as well?  Does disabling "multi-process Nightly" in about:preferences make a difference?

It does, as i noted in https://bugzilla.mozilla.org/show_bug.cgi?id=1325743#c1 with Multiprocess disabled  everything is fine

Tried to run mozregression tool several times and always hit bug https://bugzilla.mozilla.org/show_bug.cgi?id=1325199 in the end.

I can make video, but whole lot of pages looks the same. I can see some images and rarely text, when hovering cursor over page elements those i can't see at first they appear. for example on youtube hovering over video preview make some other preview disappear. Switching from tab to tab make some or all content on the page to disappear completely

[Ciprian Georgiu, Desktop QA]

I didn't managed to reproduce this issue with e10s and hardware acceleration enabled, using latest Nightly 53.0a1 (2017-01-02). 

I've tried on 3 different Radeon GPUs (see below) but, the sites mentioned in this report and also others are always rendered correctly on my side.
 - AMD Radeon HD 6450 under Win 7 x86 and 10 x64
 - ATI Radeon HD 3000 under Win 10 x64
 - AMD Radeon R7 M340 under Win 10 x64

If I can help with more info please ni? me!

Comment 13

[Ziga Seilnacht]

I can reproduce this issue on a laptop with AMD FirePro M4000 graphic card, but only when I connect to it via Remote Desktop client (and as long as I have e10s enabled). Bisection points to the same commit as mentioned previously:

But at least in my case, it could be caused by bug 1285563, autoland changeset 3d4f10649284. That change enabled hardware acceleration when using RDP and caused "RDPDD Chained DD" to be reported as inactive GPU for me. Relevant about:support data before changeset 3d4f10649284:

My situation in bug 1328496 comment 3 is also remote desktop. I'll have to check the screen when I get in to work.

Comment 15

[Wayne Mery (:wsmwk)]

ignus, ziega, did the regression test (or did you manually try) the 2016-12-18 build, to totally rule out bug 1285563 as being the cause?

Comment 16

[Ziga Seilnacht]

I used mozregression to bisect both problems mentioned in my comment; bug 1285563 (changeset 3d4f10649284) enabled hardware acceleration for Remote Desktop (Windows 7's RDPDD Chained DD), which I think was not intended.

Bug 1328496 (changeset 96cf05faacfe) is where I start seeing rendering glitches as visible in ignus' screenshots - bug 1325944 could be another report of the same issue, this time with Nvidia graphics.

The rendering glitches are not visible in safe mode (which disables hardware acceleration) for me, so it seems that the combination of both changesets is responsible for this bug to be visible in Remote Desktop sessions.

Just checked - direct viewing without remote desktop is fine. 
Then ooked again with Remote desktop - broken.

Hrm, I can't reproduce this either with, or without RDP. Could you post an about:graphics from when you're running using RDP.

The patch above should get us back the "no acceleration with RDP", but that's a recent regression; :ignus' issue would be something else.

Comment 26

I believe I have found a way to reproduce this issue, when I disable cleartype in the control panel -while running- firefox, we appear to run into this issue. I'm looking into it.

The cause for this is essentially that in the content process OnPaint events are never received and we're not appropriately updating the drawing mode.

This won't fix the bug, and I even doubt it is a good idea. I have a patch upcoming.

Attachment: Bug 1325743: Cache Moz2D ClearType usage information in a way similar to Thebes.

This patch makes sure content processes update their cleartype settings, as well as making sure Moz2D's idea of the ClearType settings are in sync with those of Thebes. If the two differ this can cause graphical glitches.

This is backing out part of the change from bug 1285563, where running RDP now reports as running the discrete card.  It could be we want to keep that though.

This looks wrong; primaryIsRDP would get set to true only in Windows 8+, where RDP hardware acceleration was enabled even before bug 1285563. The questionable part of bug 1285563 is that it enabled RDP hardware acceleration on Windows 7, where it wasn't enabled previously.

This is actually really tricky to do in Moz2D. I'll look into this but for now I want to fix the bug.

I had to back this out for being the likely cause of a bunch of reftest failures on Windows 7 VM: https://treeherder.mozilla.org/#/jobs?repo=autoland&fromchange=10841f767eaf3f85cd1804016553fdeffc07b82e&group_state=expanded&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=success&filter-classifiedState=unclassified&filter-searchStr=3fd70802c3f5b4e1bc35a83215b433bd10b2bae0

Hmm, the failures kept happening on the backout push. I guess this is safe to reland, then?

It should be, can you reland it or should I?

I'm on time off until mid next week, would be faster for you to reland it. You should just have to reopen the review request and retrigger autoland.

I tried reopening but don't have the permission; seems like the author has to (or somebody with magical powers I don't have.)
