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%.

I have the following extensions active:
- Desktop Icons NG
- Ubuntu AppIndicators
- Ubuntu Dock

Disabling all extensions didn't change anything in my case.

Also I've noticed an interesting thing: when moving the cursor, CPU usage goes up for gnome-shell AND for whatever process on top of whose window I"m moving it. 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.
