Binary package hint: compiz

When using the nvidia-restricted driver and compiz desktop effects the
vnc server will not refresh the screen. This is being caused by the
xserver not getting "damaged" by the nvidia-restricted drivers. Linked
bugs confirm this is not an issue on intel chipsets or nv driver.

Steps to reproduce:
Enable desktop-effects (default) with nvidia-restricted driver
Enable remote desktop 
Connect with VNC

Results:
You see a screen snapshot of your desktop but if you click a menu item there are no updates to the screen. 
Notes:
If you close and restart the vnc session, you get an updated snapshot but still no refreshes.

Workarounds:
Use the -noxdamage argument with vncviewer. This is really inefficient and bandwidth hungry since the whole screen refreshes.
Kill compiz and use a different wm (metacity). 

This bug has been confirmed by many others with linked reports. Might be
an issue with xorg since there is a report of ATI drivers with similar
issues in https://bugs.launchpad.net/bugs/328559 .
