xf86-video-ati + compiz = white or black screen

[Marius Groeger]

Hello all,

I'm trying to use xf86-video-ati git HEAD head and compiz fusion 
0.5.5. If I start compiz --replace, I get an all white screen. If I 
add the --use-copy parameter, I get an all black screen (with very few 
colored garbage pixels in the top half of the screen). What could be 
wrong. So far I could not find any xorg.conf option which has any 
influence on this, and the only way out the web suggests is to use 
Xgl. I don't want to resort to that because I don't like neither 
approach nor the fglrx driver which Xgl implies. Any hint greatly 
appreciated!

Thanks
Marius
