Why does my MacBook Air have an opaque box with a line in the middle that keeps appearing and disappearing on my screen? It seems to appear when I start typing but not always. It will go away for a few seconds then come right back. I cannot click on the box, it is just there. I have attached some pictures.
MacBook Air 13″, macOS 10.15
