           Summary: Explicit access to and creation of front/back buffers
                    for DirectDraw interfaces prior to version 7 needed
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P1
         Component: directx-ddraw
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: mikademus at gmail.com


In DirectDraw, the interfaces prior to version 7 allow the explicit creation of
front and back buffers. In DirectDraw7, which is the last and latest ddraw
implementation, this was changed.

Currently, the WINE implementation of ddraw seems to use the same functions for
front/back buffer handling, function that seem to be based in the ddraw7
interface and prohibits explicit front and back buffers. This breaks a fair
amount of older games which rely on earlier ddraw interfaces.
