In bug 877904 and its duplicates, the unlock screen features Unity's menu bar.
In bug 886605 and its duplicates, the unlock screen features Unity's menu bar and launcher.
In bug 916079 and its duplicate, the unlock screen is covered by a full-screen application.
I posit that bug 877904 and its duplicates are all duplicates of bug 886605, reported by people who have the launcher set to auto-hide.
I also predict that bug 916079 will turn out to be a duplicate as well, because the underlying cause will be layering of a particular type of window, not of Unity windows in particular. I predict that because, for me, the bug is 100% reproducible either with Unity *or* with the XFCE panel.
