no, actually. this is how input devices work. the physical devices are
abstracted away through the virtual core pointer. all events go through this
core pointer device, and if an application grabs it then events are no
longer sent to anyone else. same with the keyboard.
hence if you have a rogue grab, all devices seem to stop working.
