I have the same issue. I upgraded unity yesterday to the latest release "sudo apt-get upgrade unity" however it is still not fixed. This issue has been effecting me for at least 6 months, around every 4 hours of use the luncher gets stuck. It doesn't always correspond to lockerng either.
As I have a small screen disabling auto-hide is not a very useful work around. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1338696 Title: Launcher often fails to auto-hide Status in Unity: New Status in “unity” package in Ubuntu: Confirmed Bug description: Sometimes I'll use the Launcher to start Google Chrome, a Terminal, and Emacs.
