Suspicious Activity Captured On Laptop Screen

Has anyone else experienced this suspicious activity on your screen while using Facebook? Watch my mouse move across the videos and then stop on the far left. Somehow the text on those videos appears to be being scanned or captured by someone other than me. If you have experienced this post a comment. I think it's an algorithm that forgot to cloak its tracks as the scan for us terrible patriots. And for all you haters out there I am not high or drunk. but if you're holding well you know. Kidding lol, Seriously though it ain't me highlighting the text. It's too orderly to be a glitch so who is behind my screen?
