[Wine] minimap and Leaderheads not showing up in Civilization IV

[asch]

Civilization IV Beyond the Sword expansion.

I'm using Wine 1.1.44 with the latest intel drivers (2.12.0) and mesa at 7.8.2. OS is GNU/Linux, Gentoo distribution

Both the minimap at the lower left corner and leaderheads don't show up, showing just a black section on the screen instead. Also, some artifacts are showing up in forests and jungles.

This is very different from the results described on http://appdb.winehq.org/objectManager.php?sClass=version&iId=10158&iTestingId=51250.

I followed these instructions thoroughly, tried different graphics settings in both wine and game. alsto tried winetricks msxml3 msxml4 d3dx9, with the required overrides, and no improvement was noticed. If you see te screenshots from Appdb, we can see that minimaps are rendered correcly, and the wine version is the same as of mine.

I'm using an intel GMA 4500HD and I have seen claims that it rendered Civ IV under wine correctly. Also driver support for intel chipsets seems to be good on linux, and it supports opengl 2.1 and dx10 natively, and has enough horsepower for that game.

Am I missing a setting in xorg.conf? Is there a missing library on my system?

Thank you very much, posting screenshots as soon as I host them on the internet. See you soon.
