Thanks, that confirms gnome-shell's CPU usage is due to Chrome
redrawing. Moving the cursor is a different bug
(https://gitlab.gnome.org/GNOME/mutter/issues/283) so be careful to not
confuse the two.
A third and unrelated issue is that your monitor is only running at 40Hz
even though it supports 60Hz:
1366x768 60.22 + 40.03*
If that's an attempt at reducing CPU then it will certainly help, but it
will cause visible flickering and judder which you may find annoying.
You can change the display frequency in Settings.
