           Summary: Final Fantasy XI: incorrect face culling; no glitches

Incorrect face culling causes major graphical glitches.

Final Fantasy XI is suffering major graphical glitches because triangles are
culled incorrectly.

Disabling the two calls to glEnable(GL_CULL_FACE) in
"wine/dlls/wined3d/state.c" makes the glitches disappear and the game is
rendered perfectly.

I first observed this in the Debian/testing build (1.8.5-1) and also found this
to be the case when building 1.9.22 from source.

I used the Debian Linux kernel linux-image-4.7.0-1-amd64, as well as a
self-compiled 4.9.0-rc3 with Mesa 12.0.3.

GPU: "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"

The graphics flicker a lot when moving the camera even slightly, i.e. suddenly
other triangles get culled.

I'm not using any library overrides.

Correct result with glEnable(GL_CULL_FACE) commented out.

Is that the first version you tried, or do you mean it worked before?

It doesn't work correctly in either version. I haven't tried even older
versions of wine.

I've since discovered the regedit option to check floats, but that didn't
change anything.

I wonder if this is specific to Intel, as I've never seen it happen while using
nvidia hardware (with proprietary drivers).  I unfortunately don't have Intel
thingies to test with at this time.

I suppose this is quite obsolete, or is it still happening?

Also haven't seen this with AMD freebie drivers since switching away from
nvidia, but still no Intel to test with at this time.
