           Summary: Graphic glitches on rs690 in EXA and/or compositing
                    (kwin/compiz)
           Product: xorg
           Version: 7.4
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: val-gaav at wp.pl

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 CPY
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 happens while running kubuntu jaunty with  1.6 rc2 xserver, xorg 7.4
radeon driver 1.6.11, mesa 7.3  kernel 2.6.28. The same thing was reproduced in
KDE4 with kwin and in GNOME with Compiz.  Previous release of ubuntu had the
same problem, and this also happens in Archlinux.

Here is a video example (10MB) of the problem while using kwin cube effect :
