--- Comment #7 from Tomasz Sałaciński tsalacinski@gmail.com 2008-11-04 05:06:31 --- I can tell it is not related to video drivers.
After installing DirectX9 via
sh winetricks directx9
Shadows are drawn properly. Also, postprocessing works perfect (no more crash at runtime).
AFAIK MS DirectX9 cannot interfere with Linux drivers, so it seems it's a Wine's DirectX bug.
