Summary: Use of ddraw + gdi results in black client area.
           Product: Wine
           Version: 0.9.29.
          Platform: PC-x86-64
               URL: http://www.mglavionics.co.za/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-ddraw

This small application:

...uses, I believe, a combination of DirectDraw and GDI on the client area which
results in the client area being totally black. If I move another window over it
I can see some of the client being drawn using GDI and then it's immediately
erased again. If I move the window to the upper left corner of the screen I can
see the area being updated through DirectDraw.
