I had to use Proctorio for a stats class that I took, and two or three times per test it asked me to lift my laptop up and rotate it so that it could see the entire room. The worst part was that when I was done the button to return to the test never showed up. Each time this happened, I had to contact customer support to get them to unlock my screen.

The distraction this posed had a measurable impact on my scores on these tests.
