Does anyone have problems with screen flicker when playing the game through wine on Mac? I have this issue when I enter a mission. Sometimes I can get rid of it by changing the graphic settings though.. It's a bit weird. has anybody fixed it?

I set up Wine on MAC but had to change Screen Options depending on which game: DF1&2 I set to override, fullscreen, force normal windows and it stopped flickering. Play with different Screen options and resolutions.

DFLW I think I used Porting Kit. Trust me; I am no expert but got them all to work.

I hope that helps.
My problem is at least 1 & 2 don't work on my PC.
