As you can see I got this, and obviously what I want is to have the icons back. I’m on nixos-unstable channel, I know the icons worked before but since some update it got broken. I would also like to know why it is happening, since it was working before, and this is only depending on lutris, right ?
IIRC, it’s done this way on purpose. It should be inherited from your environment. Install icons for your user or system and it should remedy the issues.
Thank you, I now understand why it was working.
I’m actually on Openbox, without DE, so I have no default icon theme. I only installed the hicolor icon theme. But I don’t remember why, I also installed the adwaita icon theme (gnome). That’s why it was working, and since I removed it icons disappeared.
Now I just reinstalled it, and it’s working !
I just have another question, do I absolutely need adwaita in order to get the icons on lutris, or are there other icon themes which are more lightweight and can do the job ?
