Title:
  scaleable launcher icons scale to blurry on external monitor

Status in Unity:
  New
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  When connecting my external monitor (Dell U2713H, 1920x1080) via HDMI,
  all elements on the screen scale properly, except for the icons in the
  launcher which display a bit garbled/blurry (don't know what is the
  appropriate term in English, see attachment). Icons show normal on my
  laptop, and also the icons of the window switcher (alt+tab) display as
  expected.

  I am using the Numix Circle  icon theme
  (https://github.com/numixproject/numix-icon-theme-circle). As the
  window switcher shows the icons normally, the theme uses scaleable
  icons, and non-numix icons are affected too, I suspect it has not
  anything to do with the theme.
