Public bug reported:

Following an update of Unity to version  5.16.0 the autohide function of
the Unity panel no longer works. Moving the mouse to the left side of
the screen does not cause the panel to appear. Unity --reset does not
help nor does changing the sensitivity settings using Ubuntu Tweak or
MyUnity.

The NVIDIA driver was also updated that day to 304.43.

Im using Ubuntu 12.04.1 LTS
