Interestingly, bug 1517133 shows this issue existed before the switch to libinput. So the bug has remained consistent with both android-input and libinput backends in Mir. And the switch to libinput made no visible difference.

I have a theory that the relative motion data Unity8 is receiving might be incomplete. Because it's a nested server and subject to input resampling, meaning it will only get input events at 59Hz. It's possible we don't have sufficient logic to merge the relative motion data accurately before it's delivered to Unity8 at the lower rate.
