[Wine] [Assassin's Creed]Transparent ground

[Berillions]

Hello,

I have a graphic bug when i play at this game.
If i'm in the 4 city, i have not problem but when i'm in the campagn, le ground is transparant.

I modified all option in Regedit (Direct3D), change the Windows Version, installed d3dx9 with winetricks or low graphic option in game, i have always the same bug.

In the console, when i launch the game with WINEPREFIX=-dsound, i have these messages :
