From https://www.reddit.com/r/firefox/comments/p0tryk/youtube_videos_glitch_out_on_the_bottom_half/
Happens on any youtube video, any.
I just noticed that the glitch is part of the youtube overaly (the one with the playback controls and such). Playing the video and then waiting a few seconds for it to go away works fine.
See screenshot.

Disabling HW WebRender doesn't change anything.
User confirms that this is solved when when privacy.resistFingerprinting is disabled.

Thanks for this. This is consistent with the randomized canvas rendering we did. Hopefully we will soon get software rendering with canvas working and can do away with all the canvas annoyances.

A comment on why anyone would like to enable this config in the first place: Oddly, pressing <kbd>F</kbd> does not make the video fullscreen in Firefox while it does in Chrome.
This page suggests to do it in order to get it working.

I still have this bug in Firefox 122.0.1, the bug is still present when full screening, and setting privacy.resistFingerprinting to false resolves the issue, however, I do not see that as a suitable long-term solution.

and re-enabling it after I disabled it to test has resolved the issue??
