Could you please set a breakpoint on `menu_bar_button_pressed_cb' in
gtkutil.c, and see how many times it is called?

That callback being triggered too rapidly seems to be the most likely
problem.

By the way, are you running Emacs on Wayland?

If not, I recommend you use the regular X build instead, since it is
simply superior to the PGTK port.

Thanks.
