I was able to reproduce this on several machines running the newer XVnc version.

  1. Start XVnc like the worker does: Xvnc -depth 16 -SecurityTypes None -ac :1337
  2. Start a console in there: DISPLAY=:1337 xterm
  3. Connect over vnc to this display: vncviewer localhost:7237
  4. Connect to the SUT over ssh with X-forwarding inside the VNC display: ssh root@s390vsw157 -X
  5. Start yast with yast.ssh and observe how it crashes/does not start

Until now I was unable to find any logs to pinpoint the component which is responsible for this. I guess since other X applications (glxgears, firefox, etc) work just fine this is a combination issue with libyui and X/Xvnc.

As discussed with Nick: I rather suspect the openssh client, not so much Xvnc. Please try if you can start ssh -X installations when coming from 15.

PR with workaround suggested in bug ticket: https://github.com/os-autoinst/os-autoinst-distri-opensuse/pull/8287
Merged.

We should use this ticket to re-needle the test suite, since the workaround causes different window borders: https://openqa.suse.de/tests/3288459#step/welcome/2

Should this land into U-Team product backlog?

Nice. I'll assign the ticket to @mgriessmeier and set it to feedback since there is not much we can do from the tools-team and a workaround is already merged.

I'd not pollute this bug here too much and better offload the re-needling-task into a related ticket.
