Also note the current window resizing implementation in QtMir is
creating additional lag that shouldn't be there. Waiting for the client
to update simply takes too long. As a result, the window edges lag
behind the mouse cursor. However since Unity8 renders its own mouse
cursor there should be _zero_ visible lag between the cursor and the
screen, as demonstrated with:

mir_demo_client_target -m /var/run/user/1000/mir_socket --
--desktop_file_hint=unity8

(after you resize it... seems there's a new QtMir bug there)
