Subject: 26.1; frame display freeze
Date: Thu, 13 Dec 2018 10:32:59 +0100 (CET)

To reproduce:


Situation 1:

- ubuntu 18.04  ethernet to an intranet (10/8), and wifi to the internet
  via NATP (172.20/16).

- emacs 26.1 compiled with:

    configure --prefix=/usr/local --with-x --without-ns --with-gif=no \
    --with-x-toolkit=no --with-gnutls=yes --without-pop --with-mailutils \
    && make && make install

    (I still have the configuration and compilation logs if needed)

- open an xterm:

- emacs -Q & disown




Situation 2, thru ssh -X -Y:

- ubuntu 18.04  ethernet to an intranet (10/8), and wifi to the internet
  via NATP (172.20/16).

- virtual box 5.2.10_Ubuntu r121806

- a vm running ubuntu 14.04
  (two eth interfaces configured, one to the host eth, another to the
  host wifi).

- on the ubuntu 14.04 compile emacs 26.1 with:

    configure --prefix=/usr/local --with-x --without-ns --with-gif=no \
    --with-x-toolkit=no --with-gnutls=yes --without-pop --with-mailutils \
    && make && make install

    (I still have the configuration and compilation logs if needed)

- from ubuntu 18.04 launch an xterm:

- ssh -X -Y  to the ubuntu 14.04 in the virtual box

- emacs -Q & disown



In either situation:

this opens an emacs frame in the X server running on the ubuntu 18.04
host.

- M-x shell RET while sleep 1 ; do echo $((i++)) ; done

this displays a new line every second.

- miniaturize the emacs frame with C-z.

- unminiaturize the emacs frame (either M-TAB to the window
  manager, or clicking on the icon of emacs).

- the frame appears as it was saved, but no update of the display occurs
  anymore.  No new lines from the shell command appears.

However, things still work without display.

We can C-x 5 2 to open a new frame, and see that the inferior process
was still running.



Sometimes (notably if we keep working with a new frame), it unfreezes
after about 80 seconds, or 600 seconds, but I've seen it frozen for more
than 1000 seconds without unfreeze before I killed
it with (delete-frame (cadr (frame-list))).

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I tried reproducing this with Emacs 29, on Debian/bookworm, and was
unable to.

Are you still seeing this bug in recent Emacs versions?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
