YouTube HTML5 1080p@60fps videos in full screen are choppy, independently if the hardware acceleration is turned on or off. I've tried clean profile, I've tried these methods: https://old.reddit.com/r/firefox/comments/amy7j6/its_been_years_since_firefox_has_stutters_on/efpuhc5/ Nothing works. How can I fix this?

That is not a hardware issue - I have no problems with watching 1440p@60fps videos in chromium.

Well, I should've looked for a solution a bit longer. This solves the issue: https://wiki.archlinux.org/index.php/Firefox/Tweaks#Enable_OpenGL_Off-Main-Thread_Compositing_(OMTC)
