I noticed that on 2020.1.a22/a23, the scene view stutters quite a lot when e.g. rotating the camera. This does not occur on a21, and I can reliably go back and forth between these versions and have the stuttering appear and disappear. Before I send in a bug report and to doublecheck whether it's just me, could I ask for feedback from people who are also on OSX and have noticed the stuttering? Looks something like this: Cheers!
