Please, how to make focused buttons/items (by TABbing/arrows) actually visible in Xfce4 (4.12) using Adwaita-dark theme? It cannot be distinguished :/ and TABbing (TAB key) is not usable :/
I am selecting this theme using menu -> Appearance -> Adwaita-dark.
This is how it looks like in Thunar:
when you press TAB several times you cannot reckognize which button is focused...
I've got fresh Xubuntu 18.04.1 install.
