Bug description:
  krillin running vivid 175

  Opened a youtube video preview from the Video scope and did not interact with it
  Running top I see unity8 between 22 and 32 % and unity-8 dash between 15 and 20
  Same with music preview

  On mako running rtm 219 its over 80% combined with  unity8-dash using the majority
  When the screen turns off it continues to use over 20% cpu

  The CPU is still used when the scope is in the background

  Does not happen in a news or nearby scope preview
  Does happen with youtube ad 7digital previews
