--- Comment #6 from klinnem@gmail.com 2009-11-20 09:57:33 --- I had not been able to install the Demo via Steam, it won't show up in the mygames list.
Instead I did a fresh clean steam install (via playonlinux).
THIS "FIXED" THE SCREEN CORRUPTION.
So I assume that either Overlord1 Files or some winetricks-installed codecs/features collide with Overlord2. The fact that different from Overlord1 Overlord2 has complete sounds even without wmp installed may give a hint to the heart of the problem.
I consider this not being a general problem any more, but the consequence of a somehow messed up wineprefix-environment.
