Public bug reported: So far Calibre's Ebook viewer and Encryptr gave me this kind of problem.
to reproduce: open any of those 2 applications. What happens is that the application's icon is not properly displayed in the favorites, then the icons for other open non-favorite applications do not disappear when closed, or disappear after a very long time, and icons of newly open applications fail to appear.
