Steps to reproduce: 0. emacs -Q 1. C-h i 2. C-x 2 3. M-x follow-mode RET There is now one line missing from the display. When using `display-line-numbers-mode', this effect is more obvious. I use the tiling window manager XMonad, and Emacs is forced to full screen. It has the same dimensions as my screen, and I have no window decorations. My resolution is 2560x1440 and the `default' face is: ftcrhb:-Bits-Bitstream Vera Sans Mono-normal-normal-normal-*-16-*-*-*-m-0-iso10646-1 My guess is that the last line is displayed, but only the top few pixels are visible, so it looks like it is not there at all. When I change the Emacs window to be floating and resize manually, I can't reproduce this bug. The window size will then snap to lines and all lines are visible. This bug is reproducible with both Lucid and GTK.
