Title:
  [performance] Indicator bar animation latency is artificially high

Status in QtMir:
  Won't Fix
Status in unity8 package in Ubuntu:
  In Progress

Bug description:
  The indicator bar animation latency seems to be artificially high --
  limited to a fixed speed that it uses when you release it.

  I suggest it should be designed to move more quickly while you're
  touching it. Because in a low latency experiment today I've found I
  can make the dash more responsive than the shell's indicator pulldown:

  1. Install devel-proposed (wily) which now has Mir 0.15 and its lower latency.
  2. Lower latency further with these experimental options:
      restart unity8 QML_NO_TOUCH_COMPRESSION=1 MIR_SERVER_NBUFFERS=2

  You may have to use mako to ensure it's got the power to keep up...

  Result: Dash scrolling is now faster and more responsive than the
  indicator pulldown. The dash tracks your finger but the indicator
  pulldown seems to have it's own max speed, which is slower.
