Bug Description
When using Compiz/Unity at my external monitor's full resolution (1920x1080), my external display displays horizontal distortion. Sometimes the vertical alignment will also waver.
This doesn't appear using metacity, so it's not a hardware issue. This also doesn't appear using the next highest resolution (1680x1050).
I'm using the radeon open-source driver.
