font face/size causes minibuffer to change in size

[Luis-Henriquez-Perez]

Sometimes when I change the face or the font, then invoke the minibuffer and start moving through candidates, the minibuffer changes from one height to another. Specifically, the height of the minibuffer decreases this happens when I move from the first candidate to the second candidate, then it stays constant. This happens even when selectrum-fixed-minibuffer-height is set to t.

I still have this under observation.

Thanks, could you provide a more detailed recipe?

First, heres a gif of what I'm talking about. If you look carefully, you notice a decrease in the minibuffer size when going from the first element to the next.

As I observe this behavior more, test it on a different machine, and try just installing selectrum alone, I'll add more information to this issue. For now all I know is that this behavior happens at some point after switching the default font. Also it doesn't happen immediately in my emacs session. So I need to try to trace down when it begins to happen.

Furthermore, this minibuffer size shift only happens when going from the first to the second element. It also doesn't seem to occur with Jetbrains Mono font for some reason. However, changing the font to Jetbrains Mono and this doesn't show.

This is what I use to change the font.

(defun void/set-font-face ()
  "Apply an existing xfont to all graphical frames."
  (interactive)
  (set-frame-font (completing-read "Choose font: " (x-list-fonts "*")) nil t))
