Could this be a case of stuck modifier keys? Qemu's notion of which 
modifier keys are pressed can sometimes get out of sync with the real 
state of the keys. E.g. when you press the alt key to alt-tab away from 
qemu, it still thinks that the alt key is pressed afterwards, because it 
didn't receive the key-up event, not having focus at that point. This 
can be corrected by pressing and releasing the stuck modifier key after 
you switch back to Qemu.
