[Problem]
With dual-head enabled, the rightmost screen shows the right portion of the
screen is corrupted.

[Original Description]
I have a Sapphire X550 Radeon. I installed Lucid Beta 1.

The left monitor is 1680x1050. The right monitor is 1280x1024.

The rightmost portion of the right monitor is unusable - in the picture below
it's the black and white stripe. Only the mouse cursor shows up on it.

The middle portion between the (default) wallpaper and the aforementioned
stripe shows a trail of whatever I drag through it.

If I move the monitors from side to side instead to top and bottom I get a
smaller unusable area at the bottom of the second screen.
