Graphics glitch

[Ariaxis]

I just started playing today and I'm getting some weird graphical glitches. Here's a few examples http://imgur.com/a/2dsUe

Any ideas what could be causing it?

Could be possible file corruption in your WoW folder. You could try uninstalling and reinstalling WoW. Additionally, check to make sure all your graphics card drivers are up to date.

Could also be caused by your video card over heating. Check the graphics card to make sure it is getting proper air flow and dust is removed.

This is called "artifacting". Usually caused by overheating graphics components (usually vram). Sometimes driver issues can also cause this.
