Does it happen on Wayland too, or only X11? Is the actual primary screen changing, or is the panel the only thing that's moving? Are the wallpapers or any desktop icons on the screens also changing, or are they remaining the same?

This happens on X11 only, wayland does not work for me, black screen is the only output. I found the solution for this wayland issue, haven't tweaked my system yet. Only the panel is changing, background images and desktop icons stay in place. I checked the screen configs after the bug, all screen configs did not changed, primary one was the same, but taskbar was in the non primary one.
Thanks. Is this consistent? Does it happen every time you do it? Or did it just happen once?

Thanks. Can I ask you to set up a new user account and replicate your panel setup, and see if it's still happening there? Basically I want to see if it was caused by an issue upgrading old configs from Plasma 5 to Plasma 6.

Basically I want to see if it > was caused by an issue upgrading old configs from Plasma 5 to Plasma 6. I did the following tests: Created a 2 users via KDE Settings, a standard and an administrator. Updated and restarted the machine, then logged into the new ones and set the second monitor as primary. In the standard one the bug happened again, and in addition, the second output was not recognized after second screen lock, so suddenly only one monitor was available in that account. In the administrator one all worked without issues, bug did not happen.
Thanks a lot for testing those!
Oh I have one more question, if you don't mind: When this happens, can you make the issue go away by restarting plasmashell with `systemctl restart --user plasma-plasmashell.service` (assuming you're using the systemd boot; if not, try `plasmashell --replace`)?

Gonna test that, as soon as I get back. Just give me a cuple of days

Got back and test it, used systemctl restart --user plasma-plasmashell.service when it happened, and totally worked, also, when the bug appeared again, entering in edit mode got the taskbar back too.
I have updated the system to the latest KDE packages available in Arch repos, the bug it's still happening in the original user and the new non privileged one.
Ok great. One final question: Do you see the issue when: - You manually lock the screen with Meta+L and then unlock? - When you disable the lock screen and let the monitor go into power save mode automatically? - Only when the monitor goes into power save while the screen is locked?

Sorry for the delay, and the answer is yes to all, it happens when I lock screen via META + L, I disabled the screen lock in all the accounts and, when the monitor goes power save, it happens again.
