Summary: Looking at a portal in Portal crashes the game.
           Product: Wine
           Version: 0.9.47.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I'm running an nVidia 7600GT with 256MB of video RAM. Ubuntu Gutsy,
2.6.22-14-generic kernel, AMD Athlon 64 3400+ @ 2.2Ghz, 1 Gig RAM.

This bug pertains to Portal. http://orange.half-life2.com/portal.html

When I move my view into line of sight with a portal, the game crashes.

It may help to know that when I tried standing in the corner and not moving at
all with where the portals were set to appear appear in sight, the portals
appeared and were (mostly) rendered and animated correctly, smoothly, and
without crashing. When I moved, the game crashed.

Most of the attached log is repeating of the line:

err:d3d:IWineD3DDeviceImpl_SetRenderTarget (0x144300) : Only 1 render targets
are supported.

The log is from the command wine Steam.exe &> ~/debug.log executed from
/home/steve/.wine/drive_c/Program\ Files/Steam/.

Let me know if any more information is needed or if there's anything I can do
to help.
