I confirm that the bug is still valid with the latest wine 1.5.29 (on Kubuntu
12.10 x86_64, video card Radeon HD 5750). The problem might be related to
graphics drivers. If I use open source drivers then the game behaves as
described in this bug. If I install proprietary Catalyst drivers (from Ubuntu
repository) then I can get one of two results: 1) with
OffscreenRenderingMode=fbo the whole screen is black, but the game seems to be
running as I hear game music and can click on (invisible) menu buttons. The
only thing that is drawn is a mouse pointer. 2) with
OffscreenRenderingMode=backbuffer the game menu is drawn correctly and I can
start the new game. After the game is started, HUD elements, menus and mouse
pointer are drawn just fine, but the world view is completely black. I have
tried to change some combinations of Direct3D parameters in registry without
any success.

Also, it seems that  the black screen problem is not unique to linux+wine,
because some users seem to experience it on windows with ati video cards (see
http://forums.steampowered.com/forums/showthread.php?t=1792468). Unfortunately,
turning off antialiasing in game settings as suggested in the mentioned thread
does not fix the problem.
