Anyone know what these artifacts are caused by?

Hello, from the picture I’ve attached I think you can assume what I’m talking about. It doesn’t seem like I’ve gotten then problem until recently and I temp deleted the config files to try it out on a “vanilla” blender install and it’s still happening.

Any ideas? This is cycles rendering by the way.
