Public bug reported:
Binary package hint: nvidia-glx-177
Intrepid Ibex, using nvidia-glx-177 but problem also occurs with nvidia-
glx-173. The graphics card is an NVIDIA GeForce 9100M G (pci express,
built into laptop).
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.
