It's possible, but it's not clear that it's desirable. Pretending that
the mouse is still inside the desktop when it has left can lead to
strange behaviors too. I think enabling clipping for these apps is a
better solution.

Most likely because XInput raw events don't take acceleration into
account. I'm not sure there's a whole lot we can do about that.
