Your previous system A must have had ssh_config (or your personal .ssh/config) set up to turn on X11 forwarding by default, which is not recommended.
That's interesting...ssh_config was overwritten. Normally when a config file I've altered is overwritten during an upgrade, I expect to be told and to be given a chance to do something sensible -- and that didn't happen in the case of the global ssh configuration file. But indeed, comparing the bullseye ssh_config to the one I had in buster, I see that ForwardX11 has changed back to "no" whereas I had forced it to "yes" in buster.
You're right that making that change in the global config file was bad practice, so this time I've left the global ssh_config unchanged from the default and added an explicit
ForwardX11 yes to the entry for the destination host in ~/.ssh/config.So nothing to do with Wayland. Thanks for putting me straight and saving me a lot of frustration.
