Bug Description
At seemingly random times, gnome-shell uses 100% CPU when moving the mouse cursor over the desktop and top panel. And the frame rate drops to single figures, almost frozen.
I first noticed this in the aggregate menu but the only reliable reproducer I've found is to drag the top panel (like bug 2062538) in a Wayland session. After that, moving the mouse cursor over the desktop wallpaper rapidly makes gnome-shell use 100% CPU when usually it's closer to 10%.
The only reliable way I've found of making the bug NOT happen is to:
gnome-extensions disable <email address hidden>
but that might just be disabling the trigger (dragging the top panel like bug 2062538). So it's possible gnome-shell/mutter is still really to blame.
