Passing True for owner_events in the XGrabPointer call makes all XI_RawMotion events appear in the queue twice, with the only difference between them being the value of XGenericEventCookie::cookie. These have always been filtered out by a check in the XI_RawMotion handler, however with a mouse that polls at more than 1 kHz frequency, there also exist legitimate events that appear indistinguishable from these duplicated events. These must not be filtered out, otherwise the pointer may move at an inconsistent speed, appearing like a bad pointer acceleration implementation. Change owner_events to False in the XGrabPointer and remove the duplicate event detection code to fix this. Signed-off-by: Torge Matthies <openglfreak@googlemail.com>
