This morning I clicked on the up arrow on the taskbar and this is what came up on the screen (see the uploaded file). Can someone tell me what this is and how to get rid of it?

Have you tried right clicking on any of them to see if there is a context menu which may indicate which application is doing this?

I can speculate that this is some kind of calibration image from your video. I assume it stays there with no way to get rid of it?
If not then it could be some kind of infection.

I would say restart windows in safe mode. Then you can at least try and start identifying if there is a third party program that is causing this to happen.
