Using Ubuntu 24.04 on a Intel Core Ultra 7 155H CPU and moving constantly the mouse inside a gnome-terminal with powertop running, the gnome-shell process wakes up ~100x/sec and uses ~100ms/s CPU time!
Why does gnome-shell wake up at all when moving the mouse inside a application window? This problem exists since years and it seems nobody of the gnome project cares about. -- 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 a high frequency mouse Status in gnome-shell package in Ubuntu: Confirmed Status in gnome-shell-extension-desktop-icons-ng package in Ubuntu: Confirmed 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.
