           Summary: polygon face culling doesn't work well in DRI mode
           Product: Mesa
           Version: CVS
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]
                CC: dri-devel@lists.sourceforge.net


this issue only happens in DRI mode
when FRONT face is set to GL_POINT mode, and BACK face is set to GL_FILL mode
enable GL_CULL_FACE, and cull FRONT face
the expected result is only FRONT face being culled away.
but here we found BACK face is also affected (BACK face change to take the
color we set for FRONT face)
