This is a fork of https://github.com/swaywm/sway that replaces pango with https://codeberg.org/dnkl/fcft for font rendering. Note: do not use the master branch; use one of the fontconfig branches
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
