New update makes Firefox fullscreen videos lag.

So I first posted on Firefox reddit about an issue with fullscreen videos lagging here. It doesn't happen on any of the other browsers (I've tried edge and chrome) and the video streams fine when on any quality as long as its not fullscreen (also affects twitch streaming annoyingly). They had a recent update so I was thinking it might be a Firefox issue. Someone had replied to me that it could be a gpu issue, "The compositor was changed recently to more directly use the GPU." quoting this article. They recommended I uninstall drivers with DDU and then reinstall the drivers from the amd website. After I uninstalled it I noticed that fullscreen videos had no more lagging issues. I installed an earlier version of relive 16.x something and it was fine as well. So now I have a suspicion that it was the new update from amd drivers that were causing this issue. I'm unsure what to do because I want to watch videos on Firefox rather than some other browser but at the same time I want to keep my graphics drivers up to date. I'm posting here to see if someone more knowledgeable than me can help me out and recommend a course of action to deal with this problem.
