Package: emacs25 Version: 25.2+1-5 I have an installation of Debian testing that uses openbox as its window manager. Recently openbox was upgraded from version 3.6.1-4.1 to 3.6.1-5 which apparently broke emacs: if I open an emacs window and maximize it, then un-maximizing the window doesn't restore it to its previous size, but instead behaves as if I had manually resized it to fill the entire screen. I'm filing this bug for emacs because I have failed to find any other program that exhibits the same problem.
