Thank you for reporting this bug. The video you attached has a lower frame rate due to which it is not clearly visible to see the response of the launcher.
However, here is how it is supposed to work. On moving the mouse cursor to the left side will reveal a shadow line as you can see in the video. However to actually make the launcher appear, you need to push (apply pressure) against it. This is to avoid any false revealing of the launcher. If this behaviour is not what you experience then please comment again. ** Changed in: unity Status: New => Incomplete ** Changed in: compiz (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/965643 Title: Unity 5.8: auto-hide using mouse reveals launcher inconsistently To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/965643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
