[Bug 18956] New: Intel Xorg: no more 3D since default OffscreenRenderingMode is fbo

http://bugs.winehq.org/show_bug.cgi?id=18956

Summary: Intel Xorg: no more 3D since default
                    OffscreenRenderingMode is fbo
           Product: Wine
           Version: 1.1.23
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
                CC: [e-mail]

Wine used to self-configure itself with reasonable defaults. This is broken
since wine-1.1.23 by commit a5876bb91e92645a400a248abb1ef283d1a822f6
wined3d: Use FBOs for offscreen rendering by default.

AFAIK, fbo does not exist on the Intel i915 drivers, apparently causing Wine to
tell applications that there's no 3D!

The Westerner now reports: "R3Dgl: PICTuRE: The Westerner" "Could not find any
compatible Direct3D devices. This sample will now exit."
FIFA WM 2006 complains that it needs hardware acceleration.

Adding HKCU\Software\Wine\Direct3D
"OffscreenRenderingMode"="backbuffer"
allows these apps to start.

This failure to start surprised me, as I convinced myself long ago that setting
ORM on the Intel in user.reg had no effect. Since then I was happy to have one
less configuration setting to check to try and get apps to run ;-)

Please provide for automatic fallback fbo->backbuffer in wined3d to complete
this patch.

Using Ubuntu 8.04 or 8.10 with corresponding Intel Xorg driver.

It's supposed to fallback to PBuffer if FBO is not available, but PBuffer might
be somewhat broken. We should probably fallback to backbuffer instead of
PBuffer.

I'm puzzled. I thought my new nVidia 9400 Mac Mini, contrary to the Intel
graphics, would feature all those shaders, samplers, fbo and you name it. And
suddenly I discover that with wine-1.1.23, the Motocross Madness 2 Demo
http://www.microsoft.com/games/motocross2/ crashes after the logo picture.
Changing ORM to backbuffer avoids the crash.
I should probably file a distinct bug report and leave this issue to Intel
alone, given that other pure 3D games such as 2weistein - Das Geheimnis des
roten Drachen (demo) (not yet in AppDB) work perfectly.

Then I discover that Ctrl-e, Ctrl-a, Ctrl-n and some more of Emacs fame work in
Mac's Notepad. The Mac continue to surprise me.

Yeah, please file a separate report for that (and a backtrace would be nice
there). This bug should be fixed by fccb3d82fd5b05f0ece48e2c0547ca3357c12a2e in
current git.

Oops, forgot to mark this fixed in time for 1.1.24.
The MacOS fbo issue is bug #19049
