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

source + capplet_dialog_page_scroll_event_cb function
