Hi,
In my Pinebook Pro, testing Manjaro 20.08 sway edition installed on a microSd, I can’t change font size for gui apps. For example for wofi, libreoffice, thunar, etc…
I have change
/etc/sway/themes/matcha...
# some global theme specific variables
set $background /usr/share/wallpapers/manjaro-arm/generic/manjaro-pine64.png
set $gtk-theme Matcha-light-azul
set $icon-theme Papirus-Light
set $cursor-theme xcursor-breeze
set $gui-font Noto Sans 18
set $term-font TerminessTTF Nerd Font Mono 20
set $kvantum-theme Matchama-Light-Azul
and
/home/pablo/.config/sway/config
set $theme /etc/sway/themes/matcha-blue-pablo
all this configs works except for the gui font size
