Guide: How to fix UI scaling

[rikkarth]

Solution

In .config/hypr/monitors.conf change env = GDK_SCALE,2 to env = GDK_SCALE,1, specially if you're in 1080p monitors.

The change isn't immediately reflected, relaunch Hyprland either in System (SUPER+ALT+SPACE > System > Relaunch), if you're unsure what to do restart your computer.

Alternative Steam

This is not required if you performed the main solution successfully.

Open Steam and go to Steam -> Settings

Go to Interface and toggle OFF Scale text and Icons to match monitor settings

You should be prompted to restart Steam, otherwise restart.

I'm pretty sure changing env = GDK_SCALE, 1 solves the issue too, at least for me, since by default it runs on 2, and I'm running Omarchy on a 1080p screen. You can find this setting by navigating to setup -> monitors

I changed the windowrule from float to tile in the ./local/share/omarchy/default/hypr/apps/steam.conf file and it helped a lot.

I will provide GDK_SCALE=1 as first option to fix scaling for most applications and revamp this.

But you don't need to change the default, in fact defaults may be overwritten during updates.

I have the same issue with prusa slicer. I couldnt find any gui settings in the app or any config files.
this is my hypr/monitors.config

env = GDK_SCALE,2
monitor= DP-2, 2560x1440@165, auto, 1
monitor= HDMI-A-1, 1920x1080@144, auto-left, 1
