Be stricter with user output:

- enable again the check for monochrome pictures

- enable for the screen as well that one should not send the same identycal picture twice

Reduce impact of PiP preview on the user experience: start PiP only when the window loses focus and interrupt PiP whenever the user interacts with the page in the foreground again

Implement "ground-truth" check for proctoring to make sure that we are sending pictures

When more than 10 times the expected maximum proctoring interval has pasased without any picture being successfully sent to the server, the proctored session will be aborted.
