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.

** Summary changed:

- Mouse cursor moves way too slow in Unity 8 with a 1000Hz mouse
+ Mouse cursor is unusably slow in Unity 8 with a 1000Hz mouse

Title:
  Mouse cursor is unusably slow in Unity 8 with a 1000Hz mouse

Status in QtMir:
  Confirmed
Status in qtmir package in Ubuntu:

Status in unity8 package in Ubuntu:
  Confirmed

Bug description:
  Logging in to Unity8 on desktop (xenial) the mouse cursor moves
  glacially slow. I have to move the mouse across the whole desk to get
  anywhere. This is surprising given bug 1524145 shows the opposite is
  happening in the Mir demo servers.
