The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I've been going over Firefox profiles trying to identify the issue here and I'm not seeing it in the profiles but I can clearly see it in gpuview, so I'm going to see if I can find what these hw queue entries are that are causing it to back up every 4th vsync for a variable amount of time.

This seems to have been fixed in nightly from my testing, no longer seeing this texture copy on newly recorded profiles or in new recordings for gpuview. I don't know if it has been uplifted to Beta or Release or ESR releases, as there's been no update on this bug.
NeedInfo - Does this still repro on Firefox Nightly?

We have confirmed that this issue doesn't repro on the latest nightly build. Ticket can be closed. Thanks for investigating this and whatever change has been made shows up in the stable release soon.

This may have been caused by bug 1932772 (which is now disabled on Nightly)
