Sadly I cannot see any improvement on my machine, although, I have to admit, it is now nomore crashing.But rendering is still really slow, otherwise glxgears is giving me normal framerates (the usual fram,erates, I always got before). For me it is looking, as if there is a delay, when rendering has to be done, and then the rendering is working normal. So, closing windows, or using moving parts, is braking the system.I am running Sid and xserver-xorg-core 2:1.11.1-1 and use the nvidia driver: NVIDIA dlloader X Driver 285.05.09 Fri Sep 23 17:33:35 PDT 2011. I have an nvidia GEForce 8400 GS graphics card. I see none of these symptoms, I wonder why not...Only some cards are affected, according to Nvidia developer Aaron Plattner.

Good clue, Sven. But 'nvidia-settings -q AccelerateTrapezoids' prints nothing and so my GPU does not support trapezoid rendering and so should be affected, but I see no delay in window switching...
