27.1; iconify-frame on a Lucid build may stuck the frame |

Severity: wishlist
* To reproduce
-------------------------------------------------------------------------------
In a GUI session, with Emacs built with Lucid toolkit in a Linux machine,
do:
emacs -Q
C-z
;; select again the window displaying the Emacs GUI
-------------------------------------------------------------------------------
- You cannot insert characters in the *scratch* buffer.
- Normal movement, for intance, `C-n' or `C-f' doesn't work.
trick: `M-x' recovers the frame.
Unfortunately, when I start Emacs without the `-Q' flag, then this trick
doesn't work for me: the frame keeps unresponsive forever, and I have 2 choices:
1) Restart Emacs session (unaceptable for users).
2) Get 'blindly' (ie, without echo area feedback) a new frame:
C-x 5 b foo RET
* Expected behavior:
After `C-z' and select again the Emacs GUI you have a fully responsive
frame displaying the *scratch* buffer: you can insert characters and/or
move the cursor anywhere.
* Workaround:
Install gtk3-devel and build Emacs with GTK3 toolkit

Thank you for your guidance. It was crucial.
