--- Comment #9 from Matteo Bruni matteo.mystral@gmail.com --- The underlying bug should be fixed by d56c168da12d890b0ed3c2f22c4554d3d1140252 and 78ae4f66d7a6181499261ca4e8311de7175404cc. I can't reproduce the issue in the game anymore even with an older Wine though. I assume some game update has changed the terrain rendering somehow, avoiding the bug.
