I tested video playback on 2 Win10 PCs with latest nightly. But I could not reproduce video corruption.

It seemed that "Failure Log" had overflowed by a lot of logs. The log had only the following log. From it, I wonder if device reset might happened during video playback.

(#17792) GP+[GFX1-]: Draw framebuffer is incomplete

The Error log seemed to come from ANGLE.

Does the problem also happen with latest nightly?
Default profiler setting does not have graphics information. Can you re-capture with "Firefox Graphics" setting? Thank you.

¡Hola Sotaro!

Hope these lines find you well.

The issue was on the latest Nightly.

I also had https://bugzilla.mozilla.org/show_bug.cgi?id=1728650 around the same time, perhaps the profile there gives more of a clue.

I'm 98% sure I captured the profile in the initial report with "Firefox Graphics" setting but I might be wrong.

I will keep an eye out for the issue recurring today so keeping the ni? for a bit.

¡Gracias!
Alex

From profiler data, it seemed that "Firefox Graphics" setting was not enabled. When "Firefox Graphics" is enabled, profiler result becomes like the following. It has a lot of WR threads.

alex_mayorga, can you also try to get profiler of "Media"? When "Media" is enabled, the profiler result becomes like the following. It seems to help to see what is going on during video playback.
