Sometimes (in practically every application) black rectangles appear on different places.
When push PrintScr button, they disappear. So I can only show a foto of the screen. http://launchpadlibrarian.net/26498708/IMG_9276.JPG

Rather unusual that this is happening under ShadowFB.
Can you enable EXA acceleration and see if it occurs there?
Option "AccelMethod" "EXA"
to the Device section of your xorg.conf
When I enabled the EXA acceleration the bug does not occur anymore.
This may be similar to http://www.phoronix.com/forums/showthread.php?t=17680
Can you try
Option "UnverifiedFeatures" "Off"
I have a similar problem, but on another platform:
Architecture: intel x86-32
Video: Intel GM965/GL960
It is really difficult to take a screenshot!

Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component.
Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd
If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
Closing due to lack of response. Please reopen and move to the Driver/Radeon
component if this issue persists with xf86-video-ati
