Public bug reported:
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.
