Thanks, I think this clarifies the picture quite a bit, see below.

Right. 4 is PPosition flag, AFAIU.
The only place where we set the USPosition and PPosition flags in
size_hint_flags field of a frame structure is in function
x_figure_window_size (in frame.c), when the user-position parameter or
the top/left parameters are present in the parameters of the frame
being created. And that explains the difference between restoring
desktop and simply creating a new frame: frameset.el restores the
frames at their recorded positions, which is why the PPosition flag is
set. I think you should be able to reproduce the warning with the
likes of "C-x 5 b" and even just by starting Emacs, if you arrange for
frame coordinates to be specified in the frame parameters, e.g. with
the --geometry command-line option when invoking Emacs.
So we are back at square one: we need to understand why the warning
isn't get silenced by this:
/* Silence warning about visible children. */
id = g_log_set_handler ("Gtk", G_LOG_LEVEL_WARNING | G_LOG_FLAG_FATAL
| G_LOG_FLAG_RECURSION, my_log_handler, NULL);
Can you look into the source of g_warning and see why the above
doesn't avoid these warnings, and what should we do to avoid it?
Thanks.
