In my case I use an AMD card on Manjaro Linux (default free amdgpu driver). I can say that with Firefox 99.0.1 video on Youtube usually plays but tries going back to a lower resolution at first, also any extra system load like other tabs will cause playback to freeze and you have to restart the video. MOZ_DISABLE_RDD_SANDBOX=1 still works fine for me thank goodness, using that it all functions as intended. Hope Firefox 100 at least doesn't break this workaround, in case the final fix isn't going to make it in time which would obviously be ideal.
