[Wine] xsyon game, black textures? black flickering

[sxe]

Hi, 

the last day i tried getting the game xsyon to run. I was some kind of succesfull but there is one last problem i cannot fix by myselfe.

 Some regions / textures are black and the grass in the game is flickering.
Cause i cannot describe it better i made some screenshots so you can see how it looks. (The flickering is not visible, cause it only show up while moving)

The game is currently in closed beta so you cannot test it. I'm hoping that this is a more general problem someone knows how to fix. Anyway, here is the link the the main website http://www.xsyon.com/.
