it's not an important ticket, but jut wanting to now:
Can it be that I have a wrong version of matcha-gtk-theme on my system?
When I do a neofetch I get this output:
Compared it with the current Manjaro xfce, and there it says:
Theme: Matcha-dark-sea [GTK2/3].
I have matcha-gtk-theme:
A flat design themes for GNOME, MATE, Openbox, Unity, XFCE, Budgie
But I am also not offered an update.
