--- Comment #93 from Julian Rüger jr98@gmx.net 2008-04-15 21:04:27 --- I found out something I think is very interesting: When you play the game Mafia with native dinput8.dll, it shows this bug. However, with wine's own dinput8 it works perfectly.
Maybe thats another case where wine does mouse warping when it should not. Or its something completely different, like windoze does mouse warping in this case, too, in another place/dll, but I think Vitaliy said dinput does not warp mouse at all.
