Re: [dev] [dwm] Need help about gray windows of Java applications

I have it in my .xinitrc, .zprofile (.bash_profile) and in my .zshrc
(.bashrc). I can never remember where it should be, so that way I know
it works somewhere.

LG3D was a WM written in Java, which maximises the irony. Java apps
know how to work on it, so they work fine when they think they are
running on it. The issue has something to do with reparenting, (which
I don't know nearly enough about to explain) that some WMs (xfwm4, Gnome
etc.) do the way Java expects, while others (dwm, qtile, LG3D) do it in
a different way (or don't do it at all, I'm not sure).

TL;DR: Java apps are stupid and have to be tricked into thinking
they're on another WM to work.
