what kind of event handler is the $button->set_visibility(1) call being
made in? check that you have the correct return behavior for this type
of callback, not doing so can cause unpredictable things to happen.

if that isn't it, then try this. it is not really a solution, but
something to try to see if it fixes things in hopes of narrowing down
the problem, try placing:
while( Gtk2->events_pending )
{
        Gtk2->main_iteration;
}
immediately after the call where you set_visibility(1).

i have done things very similar to what you seem to be trying to do in
apps with Gtk2-Perl before and things worked fine so without more
information and/or seeing the relevant code that's about the best
guesses i have.
