---------------
ubuntu-ui-toolkit (1.3.1872+16.04.20160330.2-0ubuntu1) xenial; urgency=medium

  [ Tim Peeters ]
  * Set the window color as soon as the window is available, to avoid a
    flickering background when it is updated later, plus fix runtest.sh
    to work for xenial on arm. (LP: #1554897, #1439133)

Bug description:
  With silo050 if an app has a black background it flickers temporarily
  to white at startup

  What happened:
  1) Ensure you are using the latest UITK from silo050
  2) Install the linked [0] branch which has a black/dark background (similar to the Music app)
  3) Launch the application
  4) Notice as it is launched that once the splash disappears, it temporarily goes to a white backgound causing a large flicker

  What I expected to happen:
  At step 4) for there to be no flicker

  Note, I've also noticed that the indicators and scopes do the same at
  startup of the device.
