Xorg.0.log; error message probably was there right from the start / during launch

- xf86-video-ati ddx git
- drm git
- mesa git

~ amd64, Gentoo with 3.7.9 kernel


I'm running compiz 0.8* (0.9* is unstable for me and it's also not as fast & stable as 0.8* - at least for me)


- the exposé-like feature leads to a black screen

- likewise with the zoom feature

- and switching between virtual desktops (4 virtual desktops)


Behavior & animation for Expose Plugin is:

- Expo animation: Vortex
- Reflection [x]


when Reflection is activated (in ccsm) little parts of the animation can be seen on a almost entirely black screen - after the animation has finished the screen is/stays black



zoom: 
as soon as the screen is zoomed in a little it's black


switching between virtual desktops (via alt + left/right/up/down key button):
as long as compiz is showing the animation the screen is black at the beginning and end the desktop is viewable
