Solved gvim gives error on remote system

[byrnejb]

This is possibly an SSH issue or a BHyve configuration issue.

I am working on a remote host running Rocky-Linux-8 (RL8) via ssh -X and am running X-window programs. I get this error while working in them:

X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  104 (X_Bell)
  Serial number of failed request:  6476
  Current serial number in output stream:  6601

A similar error occurs whenever I press the <esc> key in gvim:

BadAccess (attempt to access private resource denied)
Vim: Got X error
Vim: Finished.

The RL8 OS is running as a BHyve vm on 13.1-RELEASE-p7. sshd_config has this: X11Forwarding yes

The local host is running 12.4-RELEASE-p2. ssh_config has this: ForwardX11 yes

What is the likely cause of this? How is it fixed.

This appears to be related to using ssh -X. If I switch to ssh -Y then the problem appears to have been solved, so far.

I have experienced the same error as OP with OpenMotif-applications. Since other graphical applications work with ssh -X, I would be interested in the root cause of this problem. Does anyone have an idea?

What is the difference between `ssh -Y` (trusted X11 forwarding) and `ssh -X` (untrusted X11 forwarding)?

What is the difference between ssh -Y (trusted X11 forwarding) and ssh -X (untrusted X11 forwarding)? As far as I have understood it, it has something to do with security, but I did not grasp the
