Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

If you disabled hardware acceleration, try enabling it.

Does it still happen in Troubleshoot Mode?
