BTW, we have a strong suspicion that Unity8 is only seeing 4%-50% of the actual mouse motion events. This is a Mir bug, but it's also unique to Unity8 as no other Mir shell uses nesting+relative motion together like Unity8 does.
So FYI, if that's correct then once we fix it the mouse will get MUCH faster and Unity8 will need to slow it down :)
