Bug #: 29122
           Summary: Sonic R has rendering (color keying) issues in
                    Direct3D mode
           Product: Wine
           Version: 1.3.32
          Platform: x86-64
               URL: http://www2.sega.co.jp/download/pc/sonicr/sonicr.exe
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: directx-ddraw
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified
   Regression SHA1: c8901d6f6253f6c97610eb1068ac4ff89758ed0a

When Sonic R is run with the Direct3D renderer, it has some rendering issues
(various objects have a green background instead of transparent) as seen in
this screenshot: http://appdb.winehq.org/appimage.php?iId=9421

The DirectDraw renderer works without this problem. According to bug 21878,
comment 5, it's a regression caused by:

ddraw: Rewrite most of ddraw using WineD3D.

Attachment 36962 from that bug fixes the issue.

The demo has the same problem. It will most likely crash on startup due to a
game bug unless the CPU power available to it is limited somehow, e.g. by
running a program with high CPU usage while starting it.
