output of wine

The menu starts fine, but at the moment of entering a battle, the loading
screen animation becomes corrupted in seemingly random ways and sometimes the
game crashes, and other times the game seems to be running, the mosue cursors
seems correct, but the screen is eitehr all black, or filled with random
polygons.

Attached is the result of one of the crashes.

clean wine 1.1.4 on gentoo AMD64, with nvidia 7300

nvidia drivers 177.70

The game is patched to version 1.2.1, it no longer requires the CD to play

The winelogs complains a lot about pixel formats, the game is configured at a
resolution of 1024x768x32

I've tried enabling and disabling vertex and pixelshaders in winecfg, but the
result seems to be the same
