@ -1778,6 +1778,23 @@ happen without any special user interaction, for example, when Emacs
restores a saved desktop. A fix is to install version 2.6.8 of FVWM,

*** ssh -X session hangs on exit after remote emacsclient -c frame is deleted.
When Emacs is configured with an X toolkit, for example,
--with-x-toolkit=lucid, and "emacsclient -c" is run over an "ssh -X"
connection, deleting the emacsclient frame (via C-x 5 0 or C-x C-c) can
leave the X display connection open.
The symptom is that after you delete the "emacsclient -c" frame and then
attempt to exit ssh (with C-d, or "exit"), ssh will hang before
returning you to the local shell. You will have to press C-c (to sever
the X connection) before ssh returns you to your local shell (that is,
the shell from which you invoked "ssh -X").
To avoid this issue configure Emacs with --with-x-toolkit=no.
See <URL:https://debbugs.gnu.org/72517>.
** General X problems
*** Redisplay using X is much slower than previous Emacs versions.
