I noticed that when I moved my mouse cursor a lot the cpu usage by gnome-shell can get as high as 75%.
I am using the most updated gnome on Fedora 31. My desktop has 128gb ram, and its cpu is i9 9900K and its gpu is Geforce gtx 1660.
What should I do to solve this issue?
update: after I installed the most recent nvida drivers, the high cpu usage by gnome-shell is gone. however, the mouse cursor movement still gets sluggish from time to time. I am not sure if this is a hardware-related issue or a driver-related issue.
