Retro Hyprland is a shader which mimics the look and feel of the old cathode tube screens. It has been designed to be eye-candy, customizable, and reasonably lightweight.
Just download the retro.frag file and put it somewhere desirable.
You can enable the shader using the following command:
hyprctl keyword decoration:screen_shader '~/.config/hypr/shaders/retro.frag'To disable it, do this:
hyprctl keyword decoration:screen_shader ''
