Public bug reported: Binary package hint: xorg
After upgrading to Natty, I have noticed a problem with my graphics. The desktop rendering becomes corrupted (see screenshot). This seems to happen at random after a couple of hours of use... I cannot find a reliable way of triggering the bug. Dragging the mouse across the screen clears the corrupted rendering, and the desktop can be seen as normal. Application windows are generally not affected, although sometimes artefacts of the corruption can be seen in areas of the window (for example the menu bar). I'm afraid I know very little about X, and how best to debug any problems. Please let me know if I can provide any extra information to help with the debugging.
