I'm sorry, the 20% part was a bit of an overstatement, after observing more I can say it's somewhere between 1% to 5%.

For example, if a Text Editor window is active, it goes up for the gedit process. If it helps, below are a few screenshots of "top" taken when I moved my mouse, with Xorg and Wayland for comparison, and a video. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2051383 Title: gnome-shell high CPU utilization when moving mouse cursor Status in gnome-shell package in Ubuntu: Incomplete Bug description: When I simply move my mouse cursor on an empty desktop, gnome-shell's CPU usage goes up from 20% (when idle) to 60%, which causes stuttering.
