Gtk3 issue, probably.

Comment 2

[Karl Tomlinson (:karlt)]

This is controlled by the GTK3 theme.

You can override by putting this in ~/.config/gtk-3.0/gtk.css
(though styling may not be perfect), or using a theme that doesn't hide the buttons.

.scrollbar {
    -GtkScrollbar-has-backward-stepper: true;
    -GtkScrollbar-has-forward-stepper: true;
}
