Title:
  Dragging icon from dash to launcher on other monitor causes window
  stacking to get messed up

Status in Unity:
  New
Status in “unity” package in Ubuntu:
  New

Bug description:
  I have a dual-monitor setup - my laptop screen, and an external
  display to the left. I have launchers configured on both monitors. I
  can reliably get compiz to mess up the window stacking order by
  following these steps:

  1) Move mouse to right hand monitor (laptop screen).
  2) open dash
  3) Drag an application icon off the dash, over on top of the launcher on the left hand monitor.
  4) Drop the icon on the launcher.

  At this stage, the dash pops up on the left hand monitor (that's a bug
  in itself), and clicking on the dash sends clicks to the window behind
  it.

  The dash on the right-hand monitor dissapears, and the launcher icons
  remain saturated after I've released the launcher icon.

  From this point, the only thing I can do is restart unity/compiz.

  See attached video.
