           Summary: bad graphics on dual-head screen two
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/radeonhd
        AssignedTo: lverhaegen@xxxxxxx
        ReportedBy: joachim.deguara@xxxxxxx
         QAContact: xorg-team@xxxxxxxxxxx


what happens is I start xdm and it is in cloned mode, next I log in and set the
dual-head with xrandr which results in the artefacts on the second screen
(actually DVI-I_1/digital, but since it is rightmost I call it second).  
To get rid of the artifacts I kill kwin and start fvwm (twm and openbox don't
help only fvwm) then the artifact is gone and I can kill fvwm and go back to
kwin all the while there is no new events in xorg.0.log since going from clone
to dual-head.
This even happens if I have the second screen overlap that means both are
1280x1024 and screen two is now at offest 640x0 then there is that strip of
640x1024 which is rendered correctly on screen 1 but not on screen 2.
