Title:
  [dash] wasting too much time scaling the background image while
  rendering

Status in Unity 2D:
  Confirmed

Bug description:
  While testing Unity-2D with a Pandaboard, the performance is
  relatively bad while using dash.

  Running perf to understand what is consuming so much the CPU, it's
  clear that most of the time the CPU is busy scaling the background
  image. When the GnomeBackground is deactivated from the dash.qml the
  performance improves a lot while using Dash at Pandaboard.

  Will attach the debug data that shows the issue.
