After updating from KDE 4.1.0 to 4.1.1 from the opensuse-buildservice I can't activate Compositing anymore. In 4.1.0 this was working fine, also compiz is working without problems.

If I activate Compositing in kwin, I see about 1 second a normal screen with shadows, transparent window-title etc as if it's working, but then kwin is switching back to "normal" mode.

If I start kwin from a console, I get following while switching:
