SUMMARY When using Thunderbird, treeview icons are white on a white background (not visible) It makes Thunderbird barely unusable. Fetching gtk.css for the bug, I identified this issue: treeview.view.expander { min-width: 16px; min-height: 16px; -gtk-icon-source: -gtk-icontheme("pan-end-symbolic"); color: @theme_base_fg_color; } The color @theme_base_fg_color is undefined and should be #31363b for instance.
