>Description:
X-window pixels are garbled when using certain applications like VirtualBox or netbeans. This started with xorg-7.5
>How-To-Repeat:
1. Start VirtialBox and move the scrollbar on the right side. The whole text will be duplicated, writing the moved image on top of the original.

2. Open netbeans ide either version 6.8 or 6.9.1 and to 'show changes' on a whole project. Then press 'diff all' and step through the changes. At some point one or both windows (showing the original window or the current version) will be messed up.
>Fix:
unknown!
