--- Comment #3 from eserradi@gmx.com --- I reverted commit b4fea4f2f0df40976f50d396e9e4046929697879 and after applying and recompiling wine 5.0.2 the problem with the mouse has been solved, it is working again. The patch I used is attached as a workaround until a proper solution is merged in wine 5.x, thanks a lot!
