I am also experiencing this bug. I think this may also be related to a problem I am seeing with Ubuntu 12.04 running in Virtualbox (with an Ubuntu 12.04 host) in that I cannot get the launcher to show at all in Virtualbox unless I use Unity 2D.
For the record, my system is running Ubuntu 12.04 and GeForce 9400 GT/PCIe/SSE2.
Turning off auto-hide is a temporary fix, so I will wait for an NVidia patch to become available.
