Summary: opengl in qt window does not display
           Product: Wine
           Version: 0.9.26.
          Platform: PC-x86-64
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I want to run a large, commercial, qt-based 3d app (gocad, earthdecision.com)
under wine. It starts up fine and display its main window with menus and
toolbars. However, the 3d viewing area is never updated, no objects are
displayed. The app doesn't crash and everything else seems to work.

Other windowed 3d apps like mview ( http://mview.sourceforge.net/ ) or
fullscreen apps like glview ( http://www.realtech-vr.com/glview/ ) work on my
installation.

I compared +opengl,+d3d,+wgl debug output from mview and gocad (attached). It
appears that gocad wants first a stereo capable display:

trace:wgl:dump_PIXELFORMATDESCRIPTOR   - dwFlags : PFD_DOUBLEBUFFER
PFD_DRAW_TO_WINDOW PFD_STEREO PFD_SUPPORT_OPENGL
...
trace:wgl:ConvertPixelFormatWGLtoGLX Number of offscreen formats: 60; returning
index: 2
trace:wgl:X11DRV_ChoosePixelFormat stereo mismatch
trace:wgl:X11DRV_ChoosePixelFormat No matching mode was found returning 0

and then looks for a non stereo display

trace:wgl:dump_PIXELFORMATDESCRIPTOR   - dwFlags : PFD_DOUBLEBUFFER
PFD_DRAW_TO_WINDOW PFD_SUPPORT_OPENGL

However, there is no matching X11DRV_ChoosePixelFormat following that. In any
case the full debug, without the fixme: lines and truncated after it seems to
starts draw things is attached.
