This problem doesn't show up if OffscreenRenderingMode is set to 'fbo', but
does for 'backbuffer'.

Well, not exactly disappears... With fbo the problem remains, but only partly,
as in the next screenshot.

I couldn't reproduce this problem here (wine-1.1.37+). What's your wine
version? Is it really wine-1.1.37?

Geforce 8800GTS
NVIDIA 190.53

Sure I could say that with previous wine versions (commit
ffb38da024b044b4958d21784b5cc290291883a9 fixed it), there I could see the bug
as in picture http://bugs.winehq.org/attachment.cgi?id=25930 (with backbuffer
and pixelshader off).

(In reply to comment #5)
> What's your wine version? Is it really wine-1.1.37?

$ wine --version
wine-1.1.37

I just patched it to support INTZ, but before this the game showed the same
behavior.

Maybe this is because of virtual screen emulation... in my config it's
1280x1024. I can't check without it because the game wouldn't start.

OK, i found why you might not be able to reproduce this. When FSAA is not
forced for nvidia drivers, this problem doesn't exist. So, to reproduce:

__GL_FSAA_MODE=8 wine gta_sa

or, just set FSAA settings to override application settings and some non-zero
smoothing in nvidia-settings.

Ok, I could confirm the problem with AA enabled.

If AA is enabled, you also hit bug 14341 again.

When fbo and AA is enabled you get:
fixme:d3d:stretch_rect_fbo >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from
glBlitFramebuffer() @ ../../../git/dlls/wined3d/device.c / 5770

So then you probably wouldn't see the "wrong" dark polygons. There is no error
output in the case of backbuffer.

> Invalid - user configuration error.

Why is this configuration error? If i can use this feature on windows and
cannot on WINE, this IS WINE bug, not configuration error.
> Don't force something that doesn't work.

Nvidia's force AA mode DOES work for any other application i use, so this can't
be said to NOT work.
If something makes WINE not work, WINE should be fixed, because it is most
probably WINE bug.

Multisampling is disabled on Wine because multiple bugs in Nvidia & ATI
drivers.
