Thanks for the bug report. In your video I can see two causes that are not really bugs:

* Firefox using CPU at the same time as gnome-shell means it is Firefox causing the persistent CPU usage in gnome-shell. Make sure Firefox isn't displaying animations like web ads. Even if that doesn't look like the problem, it's still Firefox's fault if the problem is correlated with that app running.

* Triggering the window spread animation causes even higher gnome-shell CPU usage. This is normal and not a bug. Although we welcome patches to make it more efficient.

Suggested workaround: Make Firefox render more efficiently by adding MOZ_ENABLE_WAYLAND=1 to /etc/environment and then reboot. Also don't leave any browser tabs open that you don't need.
