I've compared Firefox performance during 4k Youtube video playback on 20.2.2 against 20.4.1 and on newer driver the performance became significantly worse.


An example, this video (change quality to 4k) 

Start/stop the video and scroll-up/scroll-down the page. At least on my system Firefox stutters.


Anyone encountered the same?
