M1 Mac 13 - Sluggish and laggy system animation
I've noticed a lot of sluggish and lagging system animation (launchpad, dock magnification, genie effect), and also some video lagging as well. It seems to only occur when I have an external monitor attached. Also, I did not notice this issue until I got a new 4K external monitor.
The problem goes away after restart, but returns after using graphics heavy applications such as Adobe CC apps.
My guess is that it's a GPU related issue. I notice in Adobe Illustrator the GPU preview changes to CPU preview after some time, and I can't change it back to the default GPU preview. Almost as if the GPU has shut down or is faltering.
I know others have experienced this as well. Please comment here. This is a serious issue that needs to be addressed. These machines are expensive and should work properly.
