Description

When booting up hyprland, waybar do not have transparency until launching a window.

Hyprland just booted up:

Hyprland and waybar after opening a window:

How to reproduce

You need to start a new hyprland session (without any window opened in the session) for waybar to be opaque. When a window is launched, it becomes transparent until the end of the session.

hyprland.conf needs the option layerrule = blur, waybar

waybar/config.jsonc needs to have the option "layer": "top",

With "layer": "bottom", there is no bug.

waybar/style.css needs transparency, for example: window#waybar { background-color: rgba(00,00,00,00); }

Waybar config: config.jsonc style.css.txt (I had to call this style.css.txt instead of style.css because of github restrictions).
