Login screen displays unknown user when coming back from blank screen
After updating to Ubuntu 21.04, sometimes after my screen is blanked and locked automatically and I wake it up, the login screen doesn't show my name or picture. It just shows a generic new user photo. If I enter my password, the spinning circle appears next to the password text box and gets stuck that way indefinitely. If instead I press Esc twice, I get back to a login screen with my name and picture and am able to unlock normally.
The issue doesn't happen all of the time; I think that the longer I leave my machine idle, the more likely I am to run into it, though.
Here's what the incorrect login page looks like.
And then after I enter my password and press Enter, I get stuck on this screen.
Just pressing escape while that's happening puts me back at a normal login screen.
Here are my power and lock screen settings.
And my extension settings.
I still see the same behavior when I turn off the two manually installed extensions. I'm running a multi-monitor setup with different resolutions, if that's relevant.
Syslog
Here are what look like the relevant entries.
