I have tried to user QCursor::pos() from the engine thread. First I looks very promising, but it turn out that it is a locking function which is not suitable for the engine thread. http://www.spinics.net/lists/xorg/msg53502.html
Proposed solution from this thread: using XCB! http://xcb.freedesktop.org/
For this bug this is clearly overdone. So we have to deal with the QT event queue delays :-(
