Q: Screen pixelates (green/magenta), but goes away soon after?

Hello, I have a question about my Macbook Pro.

 

Everything works perfectly fine (or seemingly so), but there are short moments when mostly green/magenta pixels appear. The pixels usually last few seconds and disappear on their own or when I move my mouse over them or until I log out and log back in. They seem to appear at random times and anywhere. At one point, they only outlined the object of my wallpaper (which is a person). They do go away so I didn't see much of an issue, but I am getting worried. Is there something wrong with my laptop that needs to be fixed?

 

I'd really appreciate your help.
