Comment 13 for bug 948938

According to this ( http://bugs.winehq.org/show_bug.cgi?id=30057 ) bug report, any application needing mouse warp or window clipping is broken with Wine 1.4 and any xserver from 1.11 to 1.12 and later.
Many 3D apps controlled by mouse are affected, and as a result are unusable.

According to Wine developper Alexandre Julliard : "The devices claim to report relative motion but they send absolute coordinates. I don't think there's anything we can do about that, you'll have to report it to xorg."
