Title:
  Programmatic slider movement is jerky

Status in Ubuntu UX:
  New
Status in ubuntu-ui-toolkit package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 15.04 r51

  1. In System Settings, navigate to Brightness.
  2. Turn on "Adjust automatically" if it is not on already.
  3. Go into a much lighter or darker environment, for example by turning lights on/off.

  What you see: The slider pops suddenly from one point to another.

  What you should see: The slider slides smoothly, accelerating as it
  leaves its previous value, and decelerating as it reaches its new
  value.

  The brightness slider is just the first ever example of this: it
  should be a general property of sliders whenever their value is
  changed non-interactively.

  It may save time to fix bug 1388094 at the same time as this bug.
