Bug Description
When going from single mode to extend using 'disper -e -t right', the new display shows up fine, but the existing/primary display shows the bottom half black, and the display area seems to be 'shifted up' 50%, so I only see the bottom half of my desktop on the top half of the monitor.
I'm using MBP 5,3 with a Mac Cinema external display with disper 0.3.0. This does not happen consistently. Maybe once every 30 times I use 'disper -e'. Once it does happen, it seems to repeat every time I switch modes, until I restart Xorg.
$ disper -v -e -t right

This may be related to unity. If I do a 'unity --replace' it seems to fix the primary display to not be offset 50% too high.
