You probably should start by setting a breakpoint in popup_get_height (https://github.com/Gnucash/gnucash/blob/58d37b75b09e71805bc0bc932866b00e5051bd94/gnucash/register/register-gnome/datecell-gnome.c#L650) to see if it's getting a sane value.

I already gave you a link to the documentation, here's where the sources live for Gtk3, the version of the library that GnuCash uses: https://gitlab.gnome.org/GNOME/gtk/-/blob/gtk-3-24/gtk/gtkcalendar.c <https://gitlab.gnome.org/GNOME/gtk/-/blob/gtk-3-24/gtk/gtkcalendar.c>, and here it is in the current Gtk4 master: https://gitlab.gnome.org/GNOME/gtk/-/blob/master/gtk/gtkcalendar.c <https://gitlab.gnome.org/GNOME/gtk/-/blob/master/gtk/gtkcalendar.c>. Not deprecated. It's on your system, GnuCash wouldn't even compile if it wasn't.

Sorry...  last time I wrote any C[1] was over 45 years ago.  I'm really
trying to figure this out...
  [1] Compared to today, C was extremely primitive back then.

Does gnucash use dbus to talk to GtkCalendar?

I normally see lots of konsole "noise" (firefox nightly in particular); so
wasn't paying attention to those messages... Just noticed this one each
time I start gnucash (4.4 & 4.8): 
  (gnucash:3896915): dbind-WARNING **: 08:21:57.808: Couldn't register
  with accessibility bus: Did not receive a reply. Possible causes
  include: the remote application did not send a reply, the message bus
  security policy blocked the reply, the reply timeout expired, or the
  network connection was broken.
Now that I'm watching, also seeing this message when starting emacs and
claws-mail...

>But your problem is more likely to be with the popup that wraps GtkCalendar than with GtkCalendar itself.

The puzzling part is that the calendar just disappeared one day a few
months ago while still on 4.4; so likely something external in libgtk
and/or dbus updates..?
