Tree views don't show expand arrows

[alexisvl]

(sorry, not sure what these are actually called)

Tree views, or at least some of them, don't render the arrows (or was it a +/- on w95? i genuinely don't remember lol). You can still click on the empty space to expand/collapse.

Can confirm, there shoulf be + and - signs, but there aren't any.
How it should look:

How it actually looks:

Something must've changed in the way Xfce 4.18 handles treeviews that is causing this.

I managed to fix it (at least for Thunar, haven't tried it for anything else yet):

1. Drop the contents of this archive into your ~/.icons/Chicago95/actions/16/ folder.
2. Update your icon cache (sudo gtk-update-icon-cache ~/.icons/Chicago95/)
3. Add the following lines of code to your ~/.themes/Chicago95/gtk-3.0/gtk-treeviews.css:
   treeview.view.expander { -gtk-icon-source: -gtk-icontheme("treeview-closed"); } treeview.view.expander:selected { -gtk-icon-source: -gtk-icontheme("treeview-closed-inverted"); } treeview.view.expander:checked { -gtk-icon-source: -gtk-icontheme("treeview-opened"); } treeview.view.expander:checked:selected { -gtk-icon-source: -gtk-icontheme("treeview-opened-inverted"); }
   And then reboot.

Done!
