--- Comment #4 from GyB gyebro69@gmail.com 2011-10-29 12:56:45 CDT --- Still an issue in 1.3.31, but already fixed in git (wine-1.3.31-172-g7df0245): the mouse pointer appears normally, without flickering with the current git version.
According to my testing this was fixed by http://source.winehq.org/git/wine.git/commit/8330558e125c9073068ffbd7741f112...
Please try the game with a Wine version >=wine-1.3.31-53-g8330558 and report back what you find.
