Well the problem is that the "Your screen is being observed" message is not real-time.

A case which I investigated myself many times is that there is no warning in login screen. I cast my screen to Google Chromecast using Chrome browser, I go to login page, "Your screen is being shared" message is there, I get back to Chrome, turn off casting, go to login screen, "Your screen is being shared" message is still there which is not supposed to be there. This is definitely a bug. It was there in MacOS Big Sur, and IS still there in MacOS Monterey.

It should be fixed.
