Yes, I was recording a presentation just like your sample youtube with a presenter on camera and ppt slides sharing the screen.. I later found that when I changed the camera capture resolution to 640 x 480 (from 1280 x 720), the problem disappeared.
The camera is a Logitech C930e. Thank you for your response.
