with beryl or compiz activated, moving, with mouse, glxgears' window to 
next desktop crash glxgears with error DRM_I830_CMDBUFFER: -22.
I get this error too with blender when I rotate the desktop cube.
Another way to get this error is launching "wine blender_for_windows".

"dmesg | tail -2" give this :
[ 9031.808089] [drm:i915_emit_box] *ERROR* Bad box 65407,301..171,601
[ 9031.808099] [drm:i915_cmdbuffer] *ERROR* i915_dispatch_cmdbuffer failed

I've seen a similar bug for 965G chipset, fixed in mesa 6.5.2 
(http://lists.freedesktop.org/archives/xorg/2006-November/019943.html ; 
http://lists.freedesktop.org/archives/xorg/2007-January/020826.html ;  

I have an intel 945G chipset and I am on Ubuntu Feisty, with mesa 
6.5.2-3ubuntu7, xserver-xorg-video-intel 2.0.0-1feisty1and 
xserver-xorg-core (R. Burton packages).

I wonder where I must report this bug, bugs.launchpad.net/ubuntu, 
bugs.debian.org, bugs.freedesktop.org ? and for which package, 
libgl1-mesa-dri, xf86-video-intel,... ?
