For radeon, this is most likely:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549588
https://bugs.freedesktop.org/show_bug.cgi?id=24131

There is no known workaround, you want to switch to XRender if you want to use 
effects.

I have no clue about nvidia, but the former bug seems to be radeon specific.
