How to watch the trigger for: "... session is locked or lid is closed"

[AttaInsularis]

Ubuntu 24.04.2 LTS (and same with 22.04.) Flatpak and AppImage

If the option is on/checked: Security > Lock Options: Lock databases when session is locked or lid is closed
the action is triggered quite often.
But the lid is not closed (notebook is in fixed position) nor do I lock myself out of the session.

This behavior doesn't exist at all until it does now, don't know for how long - months.

Since it may be a some mistake, misconfiguration or combination of a additional software on my machine - would like to ask, how can be the status of those two conditions somehow properly logged/watched?

If something is triggering this, it does bother me having no knowledge of such process existing within my machine.

(If the option isn't on, all is good, but it's more tedious work to remembering all the time for manual lock.)

Have no: dim, blank for screen, no battery or power saver.
