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).

I think it's due to either RAM or GPU load. I simulated a full CPU load, and wasn't able to reproduce this.
