Bug Description
Ubuntu Trusty r188
1. Access any of the brightness sliders: in System Settings > "Brightness", or System Settings > "Battery", or the Battery menu (bug 1289470).
2. Rapidly slide the slider from minimum to maximum and back again, about ten times, then let go.
3. Wait.
What happens: The phone repeatedly dims and brightens over several seconds after you stop touching the slider.
What should happen: The current brightness level is always either on, or less than ~500 ms from reaching, the brightness shown by the slider *right now*. Any values that the slider was on previously should be ignored.
Compare bug 1306499, the equivalent problem with the volume slider.

Marking as "fixed" for indicator-power since the brightness slider was removed for 14.04. ;)
mpt, are you seeing this behavior in system settings as well? If so you may want to add that package to this ticket.
