Subject: 27.1; X protocol error: BadMatch (...) on protocol request 73
Date: Sat, 28 Nov 2020 20:36:06 +0100

This looks like a regression since it has happened only since using
Emacs 27 (I had Emacs 26 running since a long time).

From the local machine, I run ssh on the remote one.  I launch Screen
and then I execute Emacs in text mode.  I use Screen remotely via ssh.
From the text frame I create an X frame running on a remote Xpra server
(which is a sort of Screen running on X), and I use the Xpra client
locally.

So I have an Emacs text frame on Screen and an X frame on a local Xpra
client.

I use (setq browse-url-browser-function 'w3m-browse-url)

Sometimes, when I use browse-url on an http URL, the X frame dies, but the
text frame stays alive and I can relaunch an X frame from there without
problems.  When the X frame dies, it leaves this error message:

X protocol error: BadMatch (invalid parameter attributes) on protocol request 73

Apparently this happens only when w3m does not respond immediately and
the *w3m* buffer displays a message asking to wait, but it only happened
few times until now, so I am not sure.
