Bug Description

Mir On X (mesa-x11) keeps receiving mouse movement events even when not focused.

Move the mouse outside the Mir On X window and the internal cursor keeps moving. Even click outside the window and the Mir cursor in the window keeps moving.

Confirmed this happens in Mir 0.17.1 and still in Mir 0.20.0 too so it's not a new problem with the new input stack.

This is the log output when running sudo ./bin/mir_demo_server from a x11 terminal:

[2016-02-17 08:42:39.905329] mirserver: Selected input driver: mir:x11-input (version: 0.20.0)
[2016-02-17 08:42:39.938897] mirserver: Selected input driver: mir:evdev-input (version: 0.20.0)

But to get to that situation probing of both platforms must succeed. That should only happen when you run a mir server as root within an x11 terminal without specifying a vt.

Thanks for figuring that out. I prefer the title of the bug to be in terms of what the user sees though, and not a description of the root cause.
