dri windows are in the wrong places. for example glxgear windowless in the upperleft corner shows the gears in the right place. When moving the window to the right or bottom, the gearswindow moves 3/2 as fast as the window itself. To make things worse, the gears in the gearwindow are not alligned to the window itself. The kde screen saver preview window, behaves the same with opengl screensavers. The flightgear main window is split in two when x is in 1280x1024. The left part is on the left, the right on the totaly right part of the window.
Sounds like a duplicate of bug #9965. Should be fixed in Mesa-6.5.3 and up. What version are you using? See `glxgears -info | grep VERSION`. By the way: it's better to post Unichrome bugs to the openchrome mailing list first.
