The game starts fine except that intro video and music don't play. When I load
a scenario or campaign map, the map is loaded, but the hexagonal tiles on the
map are corrupted (see attached screenshot). If you select a unit, all the
surrounding tiles become corrupted.
Another occurrence of the problem is when I load a campaign where the weather
is snowy: the map is all red and I can only see small white dots moving across
the screen (representing the snowflakes).

I can reproduce the problem with Wine 1.2.3, 1.4.1, 1.5.10. Tried the game with
the open source Nouveau as well as with the proprietary Nvidia driver (304.32):
both display tiles incorrectly.

Steps to reproduce the problem:
1. download and install the game
2. start the game and select <Play Scenario> in the menu (second button from
the left). Choose a map (it can take some time until the map is downloaded)
3. when the map is loaded you should see that tiles (hexes) are drawn
incorrectly
