Our code expects MapNotify. My reading of the code in xterm.c is that
we do nothing special when we receive VisibilityNotify.
I see in xterm.c that we already have some special treatment of the
Gnome Shell, see below. Could you please put a breakpoint there, and
tell why we don't set the frame's visible flag and don't reset its
iconified flag when the PropertyNotify event is received? Your event
log seems to indicate we get quite a few of PropertyNotify events when
the frame is de-iconified.

Thanks, this is very useful.
Here's the snippet from xterm.c that deals with PropertyNotify:
case PropertyNotify:
x_display_set_last_user_time (dpyinfo, event->xproperty.time);
f = x_top_window_to_frame (dpyinfo, event->xproperty.window);
if (f && event->xproperty.atom == dpyinfo->Xatom_net_wm_state)
{
bool not_hidden = x_handle_net_wm_state (f, &event->xproperty);
if (not_hidden && FRAME_ICONIFIED_P (f))
{
/* Gnome shell does not iconify us when C-z is pressed.
It hides the frame. So if our state says we aren't
hidden anymore, treat it as deiconified. */
SET_FRAME_VISIBLE (f, 1);
SET_FRAME_ICONIFIED (f, false);
f->output_data.x->has_been_visible = true;
inev.ie.kind = DEICONIFY_EVENT;
XSETFRAME (inev.ie.frame_or_window, f);
}
else if (! not_hidden && ! FRAME_ICONIFIED_P (f))
{
SET_FRAME_VISIBLE (f, 0);
SET_FRAME_ICONIFIED (f, true);
inev.ie.kind = ICONIFY_EVENT;
XSETFRAME (inev.ie.frame_or_window, f);
}
}
x_handle_property_notify (&event->xproperty);
xft_settings_event (dpyinfo, event);
