Gap after airline segment about telephone-line

[JSmurf]

I'm having this issue as well, with 7 or 8 characters of space after the airline segment.

This typically happens because the width of the rhs can't be calculated. I can see @JSmurf you have an icon in your mode-line; it might not have a :width tag?

I had the same issue. The problem can be fixed by setting the face height the same for the default and mode-line.

(set-face-attribute 'default nil :height 160) ;; The unit is 0.1pt
(set-face-attribute 'mode-line nil :height 160)
(set-face-attribute 'mode-line-inactive nil :height 160 :foreground "gray20")
