[Bug 12781] New: Dungeon Siege graphics problems since removing the pixel format limitation

Summary: Dungeon Siege graphics problems since removing the pixel
                    format limitation
           Product: Wine
           Version: 0.9.60
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winex11.drv
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Tested with most recent release as well as git version. As of wine 0.9.57,
Dungeon Siege does not display the main menu correctly (there's some shadow
effect which appears above all the buttons rather than below) and in game, all
the 3D elements are not properly clipped based on point of view.

This is directly related to the following patch which I used as git bisect to
narrow down to.

I am unsure as to whether this is a problem with Xorg 7.3 (server 1.4), my
Intel card using driver 2.2.1, the game itself, or wine.

I do know that I can play Neverwinter Nights natively (linux client) and it
uses OpenGL and 3D without any visual problems. As well, running Half-Life 1
via Steam.exe works and no issues in game. All using wine 0.9.60.

I am willing to try additional things to find the problem as the game is quite
unplayable since removing the pixel format limitation.
