Bug Description
In Gnome, when I hit "Super-L" my screen freezes but the image remains intact instead of taking me to a login screen.
Further, I can still access the application dock and start applications (though I cannot see the apps or interact with them) and I can interact with the top activities bar.
Maybe it's useful, maybe not, but I'm using X11 not Wayland due to an issue with my NVidia card.

I also saw the message "Screen lock is locked down, not locking" but that appears to be at hibernation/sleep rather than lock.
I also saw this AskUbuntu page, but they didn't give an indication that they'd posted a formal bug:
