Safari Flashing
I'm running macOS 11.4 and I've started to notice that when I use YouTube in Safari, the content flashes. When I leave my cursor alone and the controls for the videos disappear, my screen starts to flash like it's glitching. I've watched the same video side-by-side on Edge, Chrome and Opera and the issue is only on Safari, so it's definitely not a hardware issue. Obviously I don't want to change browsers because Safari is the fastest for my Mac. Has anyone else had this issue?
