Flickering/freezing randomly, Fedora 33

At any random time, parts of Gnome will begin flickering and the desktop may freeze. It may also continue flickering without freezing, or it might lockup for ~5 seconds and recover. Sort of a glitchy looking flicker. This happens often enough to get in the way of productivity like school work. I put in a spare drive and installed a fresh Fedora in case I had screwed up my main install somehow, but the issue was there too. I thought it was a bug with Gnome so I filed a bug report, that didn't get any attention. Then I tried installing KDE on that spare drive with Fedora which ended up having the same issue, but this time there wasn't freezing, and the glitching looked more stretchy when it happened. Anyone know what might be happening, and how to fix it? The issue started about a week or so ago.
