Summary: Missing graphics in FBO OffscreenRenderingMode
           Product: Wine
           Version: 1.3.4
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d

Telltale Games, in particular the third season of Sam & Max and the Wallace and
Gromit games, have missing in-game graphics when OffscreenRenderingMode is set
to fbo and the graphics quality is higher than the default. Switching to
"backbuffer" gets rid of the problem.

I have an nVidia 9800 GTX+ card and I'm using version 195.36.31 of the
proprietary drivers. At the default quality all looks fine, but when I raise
the quality to the maximum during in-game sequences I only see a film grain
effect. The menus and some other animations (like the space images from Sam &
Max 301 intro) display fine, but everything else is completely missing, I
assume covered by some shader effect that becomes solid (but I don't know
enough to make an educated guess).

On the other hand other games with film grain effects (from other developers),
such as Penumbra Overture and Mass Effect, worked fine in fbo mode.

Unfortunately I'm at loss at what kind of detailed information I could provide
to help developers diagnose this bug, but I can be of help with minor guidance.
