--- Comment #6 from winetest@luukku.com --- Is this wine problem at all?
The log contains lots of these errors.
WARNING: env_foliage_smalltree01_lod1.mesh is an older format ([MeshSerializer_v1.41]); you should upgrade it as soon as possible using the OgreMeshUpgrade tool.
Can you try that tool and tell if it helps?
