Problem happens under e10s and non-e10s.

Did you produce this regression window with mozregression? It would be nice to have a tighter range.

There are a bunch of build inbetween those two revisions. Can you try some of them (these are 32bit builds, I presume it reproduces there too): http://inbound-archive.pub.build.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-inbound-win32/ 1426644398/ [DIR] 1426645958/ [DIR] 1426646200/ [DIR] 1426646498/ [DIR] 1426647522/ [DIR] 1426647578/ [DIR] 1426649930/ [DIR] 1426649979/ [DIR] 1426650458/ [DIR] 1426650762/ [DIR] 1426651239/ [DIR] 1426651660/

Here's the culprit, makes sense. https://hg.mozilla.org/integration/mozilla-inbound/rev/d3380179efc1 Setting 'gfx.vsync.hw-vsync.enabled' to False stops the flashing.

Did some more testing with the vsync prefs. Seems that setting 'gfx.vsync.compositor' to false also stops the flashing. As long as one of the prefs I mentioned is set to false there is no flashing.

Don't know if it's related but Popcorn is much slower now no matter how I set the vsync prefs.

I can reproduce on Windows 7 and 8. STR: 1) Go to http://ie.microsoft.com/testdrive/Performance/popcorn/ 2) Push small on the bottom 3) Keep pushing play, see small flashes of black

I'm still kind of poking in the dark here but I have some notes: 1) Using software vsync instead of dwm composition to schedule composites can still cause the flashing to occur. It seems unrelated to using DwmFlush as a way to listen to vsync. 2) Forcing us to wait for vsync (https://dxr.mozilla.org/mozilla-central/source/gfx/layers/d3d11/CompositorD3D11.cpp?from=CompositorD3D11.cpp&case=true#1154) by changing the Present parameters doesn't change anything. 3) By disabling Dwm Composition as a Windows setting, minimizing and maximizing the window on this page specifically causes us to consistently flash the whole page black. Chrome and IE do not flash black when being minimized / maximized on this page. Firefox not does flash black on simpler pages such as reddit. 4) The places we flash black are the layers that are being invalidated during paint invalidation during the animation. 5) With the patches from bug 1145327, which ensure timestamps are always in the future, does not affect this bug but has caused weird animation problems before. I'm wondering if we're invalidating layers black then dwm composites so we see the flash of black rather than this is a fundamental problem with the silk approach on windows of using Dwm composition.

I verified that with the patch in bug 1145585, which showed the same symptoms of flashing black, this problem is fixed. Will leave open until bug 1145585 lands to get verification that this is fixed.

I cannot reproduce on Windows 7 or 8 with today's nightly (3-27-2015). Gary, can you please test again and verify that this issue is resolved for you? Thanks!

I can't reproduce it either. Any idea what might have fixed it?
