bug#63407: 29.0.90; <mouse-2> on misspelled word hangs X11

[Doug Maxey]

The setup:
- rocky-9 x86_64.
- The graphics session is running in "classic", i.e. Xorg, not wayland.
- multi-monitors joined to single display.
- emacs-lucid from locally built rpm (non-rpm local build behaves same).
- buffer major-mode does not seem to matter.
- <mouse-2> on a misspelled word.

The result is other than having control of the sprite (the mouse can
move the sprite around normally. and I can switch tty with Ctrl-Alt-N)
there is NO other input accepted.  Cannot select any other window than
the last (emacs frame in this case), and there is no keyboard or mouse
button input.  There are no visible change on the screen, no dialog box
pops up.

The net effect is that the screen is frozen, save for the moving sprite.

Have tried waiting it out overnight, with no change.

I have managed to do this several times, the simplest recovery is a
reboot (a PITA as I have lots of things open), as it seems to have
curdled something in the X server, just a log out and back in does not
seem to fix.

A workaround discovered by accident, when trying to find out the command
the <mouse-2> on the misspelled word invokes, <F1-k> when over the
misspelling, seems to stop the hang from happening after the
documentation is displayed, and the dialog box pops up when <mouse-2> is
pressed on the misspelling, and it works as expected.

bug#63407: Acknowledgement (29.0.90; <mouse-2> on misspelled word hangs X11)

Please reproduce this, preferably in "emacs -Q", then attach GDB to
the "frozen" Emacs process, and type at the GDB prompt:

   thread apply all bt

and post here everything that GDB prints as result.

Thanks.

If an X server freeze occurs and is not remedied by killing Emacs (by
logging out), it's likely not Emacs's fault.  However, that the cursor
can continue to move suggests that a stray server grab may be involved,
which can be a problem with Emacs.

Doug, would you please tell me whether you are using an X compositing
manager, or if anything unusual is printed inside the X server logs?  If
not, would you please run Emacs under a tool like xscope, redirect its
output somewhere, and send it here?

Thanks.
