This is with debian undstable xorg and blackbox, running quakeforge (http://quakeforge.net/).

When quakeforge is running full screen and updates happen in another window (eg, echoed console messages in the xterm from which I launched qf (eg, nq-glx)). This does not happen with the LLVM driver (I had symbol problems with a bad build of nouveau and wound up with the LLVM driver for a while).

a good test command line:
nq-glx +set vid_width WIDTH +set vid_height HEIGHT +set vid_fullscreen 1

where WIDTH and HEIGHT are the full size dimensions of the display. BTW, vid_fullscreen can be changed while nq-glx is running, but vid_width and vid_height cannot.

I Just tried it with blender in fullscreen mode with a compile going in another xterm and the same problem occurred.

This bug was fixed in march on xf86-video-nouveau side.

If you can't update xf86-video-nouveau, you can workaround it by disabling pageflipping in xorg.conf (see man nouveau).
