A recent update broke my arrow icons in waybar. I use a combination of Font Awesome and Noto Sans for my icons.I needed to change my style.css to use “Noto Sans” to “Noto Sans Mono”.

Ahh... That's better.

 

Also this got me to learn the spawn action in niri: niri msg action spawn-sh -- "waybar -c ~/.config/waybar/niri", which required the -- separator.
