           Summary: corrupt screen with EXA rendering on Radeon 200M (5975)
           Product: xorg
           Version: unspecified
          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

 --> (http://bugs.freedesktop.org/attachment.cgi?id=16011)
config file

EXA rendering worked yery well (no screen corruption) till commit "R3xx+:
EXA/textured video fixes" (d79040906cd25bd494feb5901f465bbd050aa923).
I played around somethings to find out what is going wrong and fond out that
the number of active pipes are calculated wrong

In my case one pipe was masked and one is marked as bad => 2 pipes

But this does not fix the issue. If I set EXANoComposite = 1 the screen looks
fine but is very slow.
