have you tried with clutter 1.6.4 as its fixed a number of rendering issues.
The system is fully updated as of today with respect to "fedora" and "updates-testing" repositories including clutter-1.6.4-1.fc15.
Joachim: is this improved with the latest updates, or are you still seeing mis rendering?
Issue has been observed again today with mutter-2.91.92-1.fc15.
I'm seeing this too (sometimes), my system has am Ati RV570 [Radeon X1950 Pro], so this may be related to using ati cards.
