Title:
  Launcher + top panel shifted vertically when plugging in second
  display

Status in Unity:
  Expired
Status in unity package in Ubuntu:
  Expired

Bug description:
  When I plug an external display into my laptop, the launcher and top
  panel are both temporarily drawn in the wrong location on the primary
  display, shifted vertically about 1" below where they are supposed to
  be (that is, they are drawn in the middle of the screen). The problem
  corrects itself without user intervention, but it remains a really
  ugly artifact. See attached video for an example.

  The top panel and launcher are drawn in the right place on the
  external display.

  This is 100% reproducible on my 13.04 system. I observed it in 12.10
  too so I don't believe it's a regression.

  I am using nvidia-experimental-310 310.14-0ubuntu2. My primary
  (laptop) display is 1440x900 and the external display is 1280x1024.
  The external display is configured to the right of the primary
  display. Both displays are vertically aligned (the panel is at the top
  of both displays).

  There are no functionality problems related to this; the external
  display works fine after being plugged in. It's just a cosmetic issue.
