On F31 with latest updates, in GNOME Settings I enabled Sharing then
Screen Sharing.
I use Remmina to connect via VNC, and it works.
But when the system, after the default 5 minutes of inactivity blanks
the screen and locks the user session, VNC session is terminated.

Can you re-connect and unlock the session?
 
While on F30 the VNC session is not terminated even if the screen goes
blank and the session is locked; I can unlock the session via VNC.

Do you use X11 in both releases? I don't know if Wayland can already work with VNC through Pipewire, so just checking.
 

I tested it on bare metal and in a KVM VM.
In addition, when I try to unlock the session, on the bare metal
machine the cursor arrow appears, but the screen stays black and the
mouse and the keyboard don't work.

You mean unlocking by re-connecting VNC, or unlocking locally? Does this happen only after the VNC use case, or always?
 

I would like to wait the GNOME mass rebuild before filing a bug (if it
wasn't already filed by someone else).

If you continue to see it after the rebuild, please file bugs and possibly even propose them as blockers. "Screen sharing" is one of the options in gnome-control-center, so it's expected to work reasonably well. Screen unlocking even more so :-)

Thanks!
