I cna't believe I'm the only one who has experienced this bug since I have consistently experienced it on three different computers using three different Knoppix versions (3.1,3.2&3.3). I get little 'boxes' appearing in the screen. On my laptop, it is bands or splotches of color mess instead of clearly defined boxes.
Anyway, I think I have found a solution but it's in German & I need a translator. Please somebody check out:

& translate to english for me.
It appears to be telling me to include the "XaaNoOffscreenPixmaps" option in XF86Config-4 which I have tried & it appears to work but I would like to know what else is being said.
Thanks
