[Bug 60447] Re: [edgy] Workspace switcher: Maximized windows have one pixel gap

[Torsten Schoenfeld]

Yes, it is the panel.  No, I don't think it's not a bug.  It makes no
sense to display a few *empty* pixel lines for the panel.  It doesn't do
that for the task list (which is at the bottom, in my case).  And it
also didn't do it for the panel in earlier versions.  I'd happily file
this upstream if I were sure it's not caused by some Ubuntu-specific
change.
