Just to update the latest behavior, Issue is still able to reproduce it on Windows 10 using chrome latest Beta #55.0.2883.59. trchen@ Since this issue is marked as P1 for M55 and it will be pushed to stable soon, can we get any latest update on this issue? Thanks!

I don't know the bug mechanism exactly, but the flickering coincides with frame swapping, and no longer reproduces with layer borders on, strongly suggests that it has something to do with surface damage tracking. Reassign to cc folks for further investigation.

Ping - Jayadev do you know what the root cause was? Tien-ren: this should have been fixed before 55 went to stable.

This doesn't repro on Linux and Mac. I don't have a Windows machine around. can investigate this once I am back in Mountain View, will leave it available if someone else wants to look at this before that.

Ali, tentatively assigning to you given it may be realted to issue 671773 . If it turns out not to be then feel free to send it to Tien-Ren.

This is also caused by using the single-quad render pass optimization when the quad rect is different from the render pass' output rect. |
