Binary package hint: nvidia-glx-177

Intrepid Ibex, using nvidia-glx-177 but problem also occurs with nvidia-glx-173.

3D acceleration works fine, but there is abnormally high CPU usage for certain 2D tasks: running "sl" (the "steam locomotive" joke program) under gnome-terminal causes CPU usage to hit 50-70%, while running the same command under xterm or a non-X terminal yields around 1% usage. Moving windows around in Gnome leaves visible trails while the redraws wait for their chance at CPU time.

The high usage is always for the Xorg process, as reported by top, so this is likely a driver problem.
