This is a duplicate of #1778 #1815 #1848, but here is a solution.
I see that in mate-appearance-properties the mouse scroll works very well like 
this:

        #include <gdk/gdk.h>
        #if GTK_CHECK_VERSION (3,0,0)
        gtk_widget_add_events (GTK_WIDGET (notebook1), GDK_SCROLL_MASK);
        g_signal_connect (GTK_WIDGET (notebook1), "scroll-event",
                                        G_CALLBACK 
(capplet_dialog_page_scroll_event_cb),
                                        GTK_WINDOW (window));
        #endif

 + [capplet_dialog_page_scroll_event_cb 
function](https://github.com/mate-desktop/mate-control-center/blob/master/capplets/common/capplet-util.c#L173)
