picture of coruption

This is what happens on my toshiba a215-s7416 :

Everything is just fine while using XAA, however using any compositing manager
or EXA ends up with coruptions on the screen. The coruption is most intensive
in compositing in use , a bit smaller in EXA. Also it seems that changing CPU
mode to performance instead of dynamic almost makes those issues goes away ...
Corruption with the Turion CPU always set to 1700Mhz is quite hard to notice
and a lot smaller then when using on demand mode. 

This is basilcy the same bug as in video-ati radeon driver :
http://bugs.freedesktop.org/show_bug.cgi?id=20273

though dmesg and xorg log seem to be a bit different. Also there is an extra coruption in case of radeonhd which does not appear while running radeon driver (I've attached a screenshot of the problem)

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.
Comment 4 Jeremy Huddleston Sequoia 2011-11-07 15:20:34 UTC 
Closing due to lack of response.  Please reopen and move to the Driver/Radeon 
component if this issue persists with xf86-video-ati
