Launcher 'auto hide' not working in Unity-2d

[melrokz]

Configuring the launcher to auto-hide does not enable auto hide. Also, the launcher is misplaced a little from the top, as in the screenshot.

It does not affect Unity 3D.

Please see the screenshots before any action on this bug.

True story; happened after I upgraded too. This occurs for me, usually, after 10 minutes or so of use.
