Title:
  Launcher in auto-hide mode reveals and hides frequently while pointer
  still hovers over it on high GPU/RAM load

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

Bug description:
  HOW TO REPRODUCE:

  Open several apps at the same time to provoke a high GPU or RAM load,
  and try to reveal and using the launcher with the mouse.

  WHAT SHOULD HAPPEN:

  Windows should just grey out until responsive.

  WHAT HAPPENS:

  The launcher reveals and hides inconsistently even though the mouse is
  still hovering over it, making it nearly impossible to switch between
  windows or launch another app. It seems the launcher very frequently
  "looses ability to feel" that the pointer is still on top. A natural
  user response is to touch the edge several times to reveal it, ending
  up in seeing the launcher hiding and revealing frequently even when
  the user is doing something else afterwards.

  EXTRA INFORMATION

  This happens to me on my Samsung N310 netbook with Ubuntu 12.10 up to date. I already have upgraded from 1 GB of RAM to 2 GB so my machine could handle 12.04.
  It happens when either using the netbook screen or an external monitor, but it might still be related to Bug #1069242.

  Bug #1070735 concerns the panel glitch that was associated with this
  problem, and has been fixed.

  See attached video to understand better. Whoopsie appearing, reporting
  a Dmedia crash, is not linked to this (first time it happened).
