           Summary: Direct color dri windowed visual is causing causing full
                    black screen
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: suokkos at gmail.com
         QAContact: xorg-team at lists.x.org


Running mesa/demos/glsync that is using single buffered direct color visual.
When window is focused whole screen is black except that hardware cursor is
visible. If focus goes to another window with Alt+tab glsync is rendered
correctly in background.

Same problem did happen to gears too when it selected double buffered direct
color visual.

I did try to debug the problem:
- XQueryColors return correct looking colors (except that red/gree/blue members
are set to zero if they shouldn't be)
- Clipping Rectangles are set correctly.

Problem is visible with all r200, r300 and r600 drivers so it seems like shared
problem between radeons at least. I don't know if others drivers do have
problems with direct color.
Also same problem is visible with different window managers (kwin&metacity at
least)

My versions are:
xserver 1.6.2+git20090724+server-1.6-branch.606f6dba
mesa 7.6.0~git20090723.3b4235d4 & git self compiled git master
xf86-video-ati 6.12.99+git20090725.57f2c83a
