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

Thanks for the report!
Workaround: Disable hardware rendering by settting layers.acceleration.disabled to true on about:config and restart Firefox.

This could be a bug in Mesa 22.2. On Raspberry Pi, I saw pink videos as well:
According to this comment, this Mesa commit caused bug 1784327.

Sotaro, I know Linux isn't your forte, but could you pick this one up and manage the routing? Perhaps somebody else more expert in Linux (Robert Mader?) could help out.

FWIW, there's nothing actionable from the FF side - the only thing we can do is disabling HW-WR again on affected devices. I'd suggest to sit this one out until the Mesa devs have figured out a patch. Most users with affected hardware use stable distros with older Mesa where we don't enable HW-WR yet, so I don't expect too many duplicate bug reports.

Edit: err, with affected hardware I was actually thinking about the Raspberry Pi - there of course may be more Nvidia devices with nouveau drivers. Still, this appears to be a Mesa/NIR bug, so pressure should be on them.

If that means falling back to software webrender rather than no acceleration at all, then I would suggest that is no-op, since performance becomes awful (and AFAIK, for a while now Firefox doesn't allow disabling acceleration/webrender completely, it's either hardware acceleration or software acceleration). Unless there is a way to force enable acceleration.
