--- Comment #13 from Patrick Rudolph patrick1804@web.de --- I've investigated into this issue. On Windows every relative mouse movement is compared against the mouse threshold, more information here: http://msdn.microsoft.com/en-us/library/ee500883.aspx http://msdn.microsoft.com/en-us/library/aa227574%28v=vs.60%29.aspx
It looks like windows sends two / four mouse movements events, as soon as the threshold limits are exceeded. On wine there's only one event, with much larger values, resulting in the jumping. I'm trying to patch user32 asap and provide a patch.
