Description Peter Hutterer 2013-01-29 03:48:16 UTC
XTestFakeMotionEvent()'s second argument is the screen number. That argument however is not used in the server other than for sanity checking.

Valuators submitted is interpreted as screen-coordinates, but the screen number itself is not provided to GetPointerEvents(). When scale_from_screen() is called, it merely takes the coordinates and moves them according to the _current_ screen, not the one specified in the request.

Potential solution to this is to add the requested screen's offset and add a new POINTER_DESKTOP flag to base everything off that.
