This isn't a Garuda specific issue but Garuda XFCE4 is the most functional I've come across since moving from Ubuntu 18.04. I am simply hoping someone can shed some light on what's going on and where the issue actually lies.
Themeing is broken on any xfce newer than 4.12. I've seen the code change where they stopped enumerating XScreens. I was hoping someone here might be able to help point me in the direction of actually fixing this and perhaps even submitting a patch, something I've never done before.
