Like everyone else. Same issue. Noticed while sculpting, and then vector painting. Easy to replicate. M1 MacBook Air 7 Core GPU model. Everything still works, just annoying. I don't know for sure, but I wonder if this has to do with Apple not supporting OpenGL anymore and there being something that is broke with what ever version we have on MacOS now. Curious to see how that pans out with Apple supporting Blender financially and with Devs
