It has DDraw problem, screen goes black and in windowd mode, mouse leaves pink trails which making game unplayable. i tried on linux with wine, same thing, it appears that deadlock 2 1.0 (CD Version) perfectly runs on windows. only steam and gog version does not. i tried also with dxwnd, it fixed some problem like black screen and pink trail but whole screen flickers making it unplayable. i didnt test, on windows 95, 98, 2000, xp, vista, opensuse, ubuntu, debian.
