No, I don't.
With the patch, I get MapNotify right after I hit `C-z'.
That seems to be OK when I start with `emacs -Q', but it doesn't help
if I start emacs loading my custom stuff.

[This seems to be a problem affecting only my window manager (GNOME Shell)]
- After C-z, the frame dissapear from the screen.
- Note, there is no lower/upper bar with the APP iconified.
- To get such a frame again, you can do it in several ways:
1. use shortcut to switch between apps (in my case M-TAB)
2. if you the current focused window is another Emacs frame, then you
can use the shortcut to switch between windows of same app
(in my case M-`)
3. Click upper-left corner menu 'Activities': now you can click in the
'iconified' frame with the mouse
Any of those 1-3 send the MapNotify
I have tested with other window managers in several OSes (Centos 8.1,
Ubuntu 18.04/20.04).
All window managers but GNOME Shell send the MapNotify
_right after_ you land in the previously iconified frame; that is, I only
can reproduce the bug when I am using GNOME Shell.
Desktop window-manager bug reproduced
KDE-plasma kWin No
MATE Metacity (Marco) No
Fluxbox Fluxbox No
GNOME Classic GNOME Shell Yes
GNOME in Wayland GNOME Shell Yes
