Yes. There are basically two possibilities for Emacs to react to font size changes: a) Keep the window¹ size intact and adjust the number of text lines and columns, or b) the other way around. Emacs always chooses the latter, unless the window is maximized. For a text editor that measures size in characters rather than pixels, this is a sensible approach, but not compatible with tiling window managers. The commands to change the window size (set-frame-height and set-frame-width) also take lines and columns as parameters. > I haven't tested this, but I presume that expanding the font size might > result in a window that's *larger* than its frame, which is even worse. This is a problem even in non-tiling window managers, since the Emacs window can easily become larger than the screen if you choose a big font. Sven ¹ I say "window" although the Emacs terminology for an X window is "frame", but I want to avoid confusion with the window manager's frame. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
