           Summary: game (Myst IV) shows no graphics when double buffering
                    is on
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: uli-do(a)gmx.at


I tried running Myst IV Revelation by Cyanworlds/Ubi Soft in wine git snapshot
from 15th January (wine 0.9.4) to 6th February 2006 (wine 0.9.7). With double
buffering switched on in winecfg, no graphics appear, the window stays black but
one can hear the music. I think it is somehow related to the game using d3d9 and
rendering the video on a d3d surface.
Turning double buffering off, the video appears but with the speed of a diashow
(depth conversion).
I tried to debug, but failed to find the cause for the window staying black.
Please tell me which debugging options I should use to provide more information.
