I’ve been using my new 4K monitor on Bspwm awhile and got things almost sorted out (custom fonts in xresources), set Polybar bigger and stuff. Some elements are still very small, for example navigation buttons in PCManFM (same with Thunar) and Pamac, in Spotify everything is small. Could it be a GTK thing or something else like that?
The system is usable as is, but it would be nice to fix those little things also.
EDIT: I tried to change DPI with xrandr, but it did nothing.
