window-rewrite missing firefox icon upon boot (hyprland/workspaces module)

[Masber]

Hi, I am using waybar with hyprland, my issue is waybar is inconsistent in rendering the workspaces icons upon login. I have to kill and start warbar again in order to restore the missing icons.

hyprland instructions to start the apps:

exec-once=waybar & hyprpaper
exec-once=[workspace 1 silent] alacritty
exec-once=[workspace 2 silent] thunderbird & slack
exec-once=[workspace 3 silent] firefox

waybar hyprland/workspaces config

    "hyprland/workspaces": {
	"format": " <b>{icon}</b> {windows} ",
	"window-rewrite-default": "",
	"window-rewrite": {
	  "firefox": "󰈹",
	  "Alacritty": "󰞷",
	  "slack": "󰒱",
	  "thunderbird": "󰇮",
	  "spotify": "󰓇"
	},
        "on-scroll-up": "hyprctl dispatch workspace e+1",
        "on-scroll-down": "hyprctl dispatch workspace e-1",
        "on-click": "activate"
    },
    "hyprland/window": {
        "format": "{}",
    	"rewrite": {
        	"(.*) — Mozilla Firefox": "󰈹 $1",
        	"(.*) — Mozilla Thunderbird": "󰇮 $1",
        	"Alacritty": "󰞷 Alacritty",
        	"(.*) - Slack": "󰒱 $1",
	}
    },

These are how the workspaces looks like after boot

and this after restart waybar $ killall waybar ; waybar &

As you can see both the firefox and the terminal icons are missing even tho both apps are running

Any idea of what could happen?

thank you

Yeah, this has been an issue since the features creation and I keep wanting to take a stab at it when I have time... I basically just always do a systemctl --user restart waybar after login, for the time being. But, would rather it not be needed, obviously. It's basically all the apps that gets windows created before waybar require restarting waybar to be recognized.

no problem, I understand this is pending issue, I can try your workaround, that is not a problem.

thank you very much for your help and waybar is very cool :)
