When scrolling this web site in firefox while a youtube video playing in a second window you, get weird millisecond redraws of the pages elements all over the place.
The page is correct once you stop scrolling.
Doesn’t happen with youtube and other websites and doesn’t happen with this site and other video sites. Doesn’t happen all the time but seems worse the longer a video has been playing. Seems to go away if you stop the video.

AMD Rezen 7
Firefox 124.02 with and without hardware acceleration.
EDIT:
I suspect this is being caused by a 165Hz refresh rate that’s catching an unsupported positioning hack. Haven’t been able to confirm or deny by setting the refresh rate yet.
