Exactly. My patches fixes _only_ an Emacs -Q session: for me,
it doesn't work in a normal custom session.

Sorry, for the confusion. It redisplay normally in a `emacs -Q` session only.

I have tested a rich casuistic: MapNotify is never recived in my 'custom
sessions'.
Following tables summarizes the situation:
=== window manager: GNOME Shell ===
--- unpatched Emacs-27 ---
emacs -Q custom libs
MapNotify at never never
bug? yes yes
--- Emacs-27 with patch ---
emacs -Q custom libs
MapNotify at iconify never
bug? no yes
=== window manager: Other than GNOME Shell ===
--- unpatched Emacs-27 ---
emacs -Q custom libs
MapNotify at de-iconify de-iconify
bug? no no
[In this case patched/unpatched makes no difference]
Except for GNOME Shell, for all win managers that I have tested,
the MapNotify comes always at the moment of de-iconify.
In Summary:
- The bugs happens when Emacs is compiled with Lucid and run in an
environment using GNOME Shell as window manager.
- The patch works for `emacs -Q`
- The patch doesn't work in my cursom sessions :-(
Possible workarounds for me right row:
1. Use a different window manager.
2. Or, compile Emacs with GTK.
