After migrating from emacs 27.2 to emacs 28-1 (default versions in 
Fedora 35 and Fedora 36) I observe a strange behavior for the C-z 
key-binding.
It only occurs if I use fvwm as windowmanager (which is still X11 
based), and is absent if I use xfce in stead.

For emacs 27-2 all works as intended and C-z will let the emacs window 
iconify. And double clicking the iconified emacs will raise it again. No 
problems here.

But for emacs 28-1 the C-z command works only once. If I raise emacs and 
try again to issue C-z it does not iconify, but looses focus in stead.
Also after regaining focus by moving the mouse out and back in to the 
emacs window, C-z does not return to its intended behavior.

I tested with the standard Fedora versions:
   emacs-1:27.2-9.fc35.x86_64
   emacs-1:28.1-2.fc36.x86_64
on a Fedora 36 workstation installation.

I also tested this by downloading the emacs sources for versions 27-2 
and 28-1 and compiling it myself, and the situation does not change. The 
bug is present in version 28-1 and absent in version 27.2.
So there is no relation to the Fedora packaging process. It really seems 
to be a bug inside emacs itself.
