[Wine] [Assassin's Creed]Transparant ground in Kingdoms

[Berillions]

Hi,

There is a problem with this game since many versions of wine.
The game runs completly without problem but there is a graphical bug when the
character is in the Kingdoms.

In the 4 city : Damas, Jerusalem, Acre and Masyaf, there isn't this problem,
the ground is visible correctly.

This is the log (output console) :

This is a screen with the graphic bug :

Thanks for your help
