Help!

Hi people, sorry if this is the wrong area, I'm new here.

So my mac is acting very strange, whenever I'm browsing the internet, or doing anything that involves clicking of my mouse, my screen goes all weird, here's a picture to show whats happening.

I can quick fix it pretty easily, by dragging my mouse across the screen twice, but it becomes a hassle after a while, and I don't want my comp. to be damaged.

Does anybody know what this is?

Do you have your monitor set for its highest ("native") resolution?

If so, then I would tell you to take that machine to a certified Apple repair facility and show them what's happening.
