I'm using a dark theme, so it's a bit hard to see, but there is a black line between the modeline and the echo area in the shot above. You can also see it between the modeline and a hydra, and the hydra and the echo area below.


Any idea what this is, so I can get rid of it if possible?

  • @displayname Sure, it's a free Mozilla font called Fira Mono. If you're using an editor that supports OpenType features (not Emacs, unfortunately), there's a modified version called Fira Code that includes programming ligatures.

Since you're using my Emacs theme and could be using my emacs.d config, I suspect you have window-divider-mode enabled, which adds this border. You can either:

  • Set the bottom border's width to 0: (setq window-divider-default-bottom-width 0)
  • Turn off the bottom border: (setq window-divider-default-places 'right-only)
  • or turn off window-divider-mode altogether: (window-divider-mode -1)

For reference, here is my window-divider-mode config, taken from core/core-ui.el :

;; `window-divider-mode' gives us finer control over the border between windows.
;; The native border "consumes" a pixel of the left fringe on righter-most splits
;; (in Yamamoto's emacs-mac at least), window-divider does not.
;; NOTE Only available on Emacs 25.1+
(when (boundp 'window-divider-mode)
  (setq window-divider-default-places t
        window-divider-default-bottom-width 1
        window-divider-default-right-width 1)
  (window-divider-mode +1))
