Those are called video artifacts, present when:

- GPU or memory gets overheated.

- GPU or memory are damaged.

If it's the second, you'll need to replace your Mac.

 

Bolded: Is there anyway of telling the difference without taking it to a Mac support centre?

 

Well, don't know if there's something like Rivatuner for Mac, but you might as well turn your system down for some minutes, and turn it on again (with a floor fan or something like that helping on cooling). If the artifacts are like the same, then it's damaged. That's the only way I can think of.
