Public bug reported: Since at least Version 4.8 KWin has a bug that creates a region of tearing in the upper part of the display. This just got worse in 4.9 and thus Ubuntu 12.10.
This bug is already filed in KDE bug tracker but is so grave that it destroys the whole user experience. The initial patch is not big, please backport it to 4.9 and update the repository.
