I don't know if this is a bug, but my Unity launcher autohide function stops working sometimes.
I have autohide enabled, and Launcher autohide works well most of the times, but now and then, the autohide stops working, and the Launcher is always present.
I go to system settings, and confirm that autohide is enabled.
I then disable the autohide, enable it again, and still autohide doesn't work.
Does anyone have the same problem? Is this a known bug?
