I have replaced the xg_set_geometry() in my Emacs with the one
above.

So far so good. (I haven't noticed any difference. (Aside from the
welcome elimination of the GTK warning message.)

I've tried closing and restarting Emacs with various frame /
window configurations (including "full screen" frames with the
title bar hidden), and the desktops restore just fine [1]. And
restoring / maximizing frames using the window decorations works
fine too.

[1] As has been happening for a while, buffers seem to be assigned
randomly (it seems) to the windows restored from the desktop file;
I'm still convinced that in the past on starting Emacs the windows
restored from the desktop file used to come up with the same
buffer in them as they had when the desktop file was saved.
