My mac says "Your screen is being observed" on the lock screen. How do I tell what app is doing this?? I've already turned off screen recording permissions for all apps in the Privacy section. And rebooted.

Update: I found the app causing the "Your screen is being observed" message! It is the drivers for the 3dconnexion SpaceMouse! Why that needs screen recording capability is beyond me.

Just incase you have a background recording going on hit CMD + Shift + 5 to stop it.

Nope, and Zoom and OBS are closed too.

Do you have any remote connection tools like teamviewer installed?

Nope, not a lot of stuff installed on this, certainly nothing that you'd expect to be screen recording

are you using a DisplayLink dock/dongle/monitor?

Nope, nothing plugged into this laptop at all right now.
I haven't connected sidecar since rebooting this time

Pesky quantum computing. (Kidding aside, have you tried Cmd-Ctrl-Esc? In theory that should cancel whatever recording is trying to happen.)
