It's supposed to appear on both. Are you not seeing that? Could you attach a photo of your multi-screen setup showing both screens while the system is lokked?

I see; now that I have played around with it a bit, it appears that the lock screen does appear on both, but the fields only appear on the screen on which the mouse pointer is first moved; this is what led me to believe that the lock screen was only appearing on one screen.

I have noticed the same behavior on 6.2.5 but I can't reproduce reliably for now.
