After upgrading from wine-staging 3.17 to 3.18, when running Spellforce, I'm
getting black square around mouse cursor. The cursor itself is visible, but it
looks like a texture transparency issue. Black square appears even in main menu
and during starting movies, and it is present during actual gameplay.

If I disable 'Enable CSMT for better graphics performance (deprecated)' in
winecfg, there is a chance that black square doesn't appear right from start,
but it may appear on some cursor change and disappear later, but it's still
pretty reproducible for me. I'm reproducing it with high chance by hovering
over gates to another map.

I've tried running wine-staging 3.17, and couldn't reproduce issue. I've also
tried running wine-vanilla 3.18 and couldn't reproduce issue either.

Native libraries: from d3dx9_24 till d3dx9_43. I've tried clean wine prefix,
issue remained.

Also, I've compared output of wine, and for wine-staging-3.18 I'm getting a lot
of following lines:

003c:fixme:d3d:surface_cpu_blt     Unsupported flags 0x80000000.

I didn't get such lines for wine-staging-3.17 or wine-vanilla-3.18.
