Bug Description
Screenlets (which are Cairo drawn widgets in an undecorated GTK window) started to flicker in Natty from early alphas and are still flickering in latest beta. It seems that invalidating GTK window causes the window to go blank for a moment and then redraw its contents. Anyway the result is hard flickering in some cases and more gentle flickering in other cases. The same code works without any flickering in Maverick.
Ubuntu Natty (development branch) 11.04
libgtk2.0-0: 2.24.4-0ubuntu2
screenlets: 0.1.3-0ubuntu1
