Greetings. How can I change interface scaling on manjaro linux? Resolution 1920x1080
version of the GNOME shell 3.30.2
in the system settings there is such an opportunity, but you can only set either 100% (which is small) or 200% (which is very large). And you need to set 125%, (the most comfortable) there is no such option in the settings, respectively, I attach the screen:

on win10 by default, interface scaling is set 125% and everything suits, here's how to fix it on the gnome, I don't understand something in general)
