Thanks for the bug report. Please:
1. Open the Extensions app and ensure only the three Ubuntu extensions
are enabled. No others.
2. Remove any locally-installed extensions:
cd ~/.local/share/gnome-shell/
rm -rf extensions
and log in again.
3. Check to see if you have anything constantly changing on the screen.
Make sure you don't have any performance indicators/graphs running, or
web browsers open, when the problem occurs.

Title:
Without a reason gnome-shell CPU usage gets high
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Without a reason, CPU usage for gnome-shell jumps from 4% to 22%.
All I did this normal workflow, locking/unlocking multiple times over few
hours and couple of suspends.
The screenshot is showing 37% because of the screenshot tool, but idling at
22%.
And if I re-logged or reboot, it idles at 4% normally.
