I am aware of the similar sounding question: Ubuntu 18.04 gnome-shell high CPU usage
However my issue is a bit different, since it is not related to the mouse/ clock/animations because I deactivated all of those features and did not move the mouse and still could observe my issue: If I disable gnome-extensions completely via gnome-tweak-tools the following happens with my idle CPU usage of gnome-shell:
- Alt+F2+R: 10%
- Reboot: 0%-2%
Why is there a difference between a reboot and gnome-shell replace?
If I don't disable gnome-extension as such but deactivate every extension the following happens with the idle CPU usage of gnome-shell:
- Alt+F2+R: 10%
- Reboot: 10%
Why is there a such a big difference between disabling all extensions and the extension functionality itself?
The CPU usage of gnome-shell is taken when everything was idle (no mouse movement/ no seconds in clock/ no animation)
