Have you turned mouse acceleration off in your guest OS? If not, then the mouse pointer is not guaranteed to move one distance unit inside the guest for every distance unit it moves in real life. (Sorry, an unscientific explanation, but I hope it suffices.) In fact, when you move the mouse quickly, the pointer will move even more quickly ;-) This makes it impossible for QEMU reliably to coordinate the host and guest mouse locations.
Under Windows, IIRC, you can go to: Settings|Control Panel|Mouse|Pointer Options and to turn off the (ironically named) tick-box option: [ ] Enhance pointer precision Under X, try: $ xset m 1 which sets the mouse "acceleration multiplier" to 1, thus keeping the mouse positioning host-pixel-perfect both in regular and accelerated modes. For gpm, try adding the command line qualifier: -a 1 for similar reasons to the xset command above.
