When I reboot I get a fresh login screen for several seconds before the reboot starts

[Chris Green]

When I reboot my system (running xubuntu 24.04) either from the menus
or from the command line ('sudo reboot') the GUI shuts down and I get
my standard GUI login prompt for several seconds before the reboot
actually starts.

I'm pretty sure this didn't happen on versions before 24.04.

It's also a bit confusing, the first time it happpened I actually
logged back in again and then system rebooted after I'd logged back in!

Is this a bug in 24.04 or what?
