I'm currently playing StarCraft II: Heart of the Swarm and I have alot of graphics tearing. I never had this problem when play StarCraft II, but ever since I installed the expansion this has occured. 

As you can see below 'Sarah Kerrigan' has a square around her, with many dots. There should only be 1 dot and that should be underneath her... and there shouldn't be a square...

Any help to fix this would be greatly appreciated. Virtual Sync doesn't fix this issue either. Please see below for my System specs.
