This bug was fixed in the package clutter-gtk - 1.8.4-2
---------------
clutter-gtk (1.8.4-2) unstable; urgency=medium
[ Daniel van Vugt ]
* Fix high CPU usage (particularly in Wayland sessions) when clutter redraws.
Hardware redraws of the clutter stage were unexpectedly triggering software
redraws of the backing window and its decorations. On _every_ frame.
This halves the CPU usage of totem and gnome-maps. (LP: #1698282)
