After updating my year old M1 MacBook Pro i suddenly face these really weird cursor glitches. The cursor jitters and sometimes it feels like working on a 15Hz screen. See the attached video, it is only visible when capturing the screen with my iPhone, macOS screen captures look normal. It goes away after ~3 minutes and comes back randomly, but almost always after logging in/opening the MacBook. I double checked the mouse cursor stuff under the accessibility and even reset them. I'm on the latest OS, no beta or anything. Anyone has seen something similiar?
