How do I change the fade-out time of the Rofi application launcher?

[NathanPB]

TLDR: Does anyone know how I could achieve changing the fade-in/fade-out animation duration of Rofi?

I'm sorry if I'm referring to the wrong thing or saying something that doesn't make sense, I'm fairly new to hyprland ecosystem and I'm not familiar with the tools.

I'm very annoyed with the time that the Rofi application launcher (default SUPER CTRL, RETURN) takes to fade-out once you close it, either by pressing the key binding again or by launching some application. The fade-in time is just right, but the fade out takes like half a second, and it gives me the impression that my system is slow.

I tried messing with the files in .config/rofi/config and .config/hypr/conf/animations, but all that I could get is my session to completely crash, throw me into the login screen, and refuse to load back (I fixed by going into the TTY and reverting the config changes). I also went through Rofi man page but the most promising that I could find was timeout options, that is not what I want.

Thansk everyone,

Considering how late this is, it may not be of use to you, but for anyone else with the same problem who finds this, I figured out that the animation of Rofi fading in and out is tied to the values of animation = fadeLayersIn and animation = fadeLayersOut in the hyprland.conf file. Setting them to 0 will remove the animation and the speed can be adjusted as well. Other programs may also utilize these animation properties though I've only been on hyprland for like a week so I don't know what else will be affected by turning it off. Either way I'm glad I'm not alone in finding that fade animation annoying lol.

UPDATE:

I found an even more precise way to disable the rofi animations without affecting anything else that utilizes the fadeLayersIn and fadeLayersOut values. In the hyprland.conf file, you need a layer rule with no_anim set to on for the namespace rofi.

Add something like this to the end of your config file and it should disable the fading for rofi without affecting anything else that might use the animation:

layerrule {
    name = nofadepls
    no_anim = on
    match:namespace = rofi
}

I don't see any difference.
Do I need to restart?

You shouldn't have to restart. Just saving the config file should be enough to see the fade animations stop. Could you post the lines you added? It's possible your rofi has a different value, type (layer/window), or animation type, from mine. Disabling animations one at a time was how I figured out which one rofi was using. Unfortunately I am very new to hyprland and wayland as a whole so I have no idea how to figure out which namespace rofi would be using if it isn't rofi.

I put

layerrule {
    name = nofadepls
    no_anim = on
    match:namespace = rofi
}

into the custom.conf
