r363727 is firstly bout "Ganesh rendering will query onGetYUV8Planes when rendering GIF frames..", as in GIF images. Second, Ganesh is not even enabled for desktop Chrome platforms (where this bug is observed). This report is seems about video rendering (not GIF image rendering) when video transitions to full-screen mode and back. You are probably looking for some change in the video rendering stack.

Are you able to reproduce this readily? I've tried on Windows 8, chrome versions 51.0.2665.0 and 49.0.2623.75 and have yet to be able to cause this. It does look to be an animation issue in that we somehow have the stale image of the phone in place while the phone div animates back in.

Unable to repro on Linux Chrome 50.0.2657.0. The bisect range is enormous BTW, are we able to get a bisect on non-official builds for better granularity?

The is bugs appears to be due to compositor animation (CSS transform) on gray phone not drawing correctly after exiting the full screen video. See Actual_animation.mp4 in the OP at 0:23 secs (image attached). I suspect that the change was to animations ... https://codereview.chromium.org/1405993008

https://codereview.chromium.org/1405993008 shouldn't introduce any behavioral change without using compositor workers - I'm pretty confident that's not responsible here unless someone has missed reporting a precondition.
