Summary: Black screenshots in wow d3d with
                    OffScreenRendering=fbo
           Product: Wine
           Version: 1.1.22
          Platform: PC
               URL: http://www.worldofwarcraft.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When you do an ingame screenshot in WoW running under d3d, if
offscreenrendering is set to fbo, the following error is spit out:
fixme:d3d:stretch_rect_fbo >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
glBlitFramebuffer() @ device.c / 6994

The produced screenshot is completely black. This happens at least as early as
wine-1.1.11 - haven't tested with earlier versions but I don't think it's a
regression.
