** Description changed: Dual-head display (Matrox G450, Xinerama, 1280x1024 on each screen). The problem appeared immediately after migrating from drapper 6.06 to edgy 6.10 - When moving a window the window fast enough on the secondary screen, the "trailing" effect behind the window is not erased from the desktop and leaves random patterns behind (on the desktop background).

When moving the window very slowly, the problem does not happen. Displaying then closing any window on the garbled desktop repaints the desktop background. A much less frequent form of the problem is that once in a while, a graphical object is painted garbled in an application window (for instance, the Google logo in Firefox). In this case, the garbled spot is exactly the rectangle that should have contained the graphical object.
