As the opencompositing guys didn't get the same effect I checked every setting in ccsm again and by enabling the glib main loop support it seems that the problem is now gone. I did this before but enabling glib main loop actually needs a session restart to take effect.
I will close the bug report with this comment. Hopefully this report helps others running in the same problem to solve it more quickly...
