sorry to resurrect the thread, but I'm also getting the same issue. Last night I noticed that my ATI control center had disappeared so I reinstalled it it fixed several graphic errors I was getting. I did notice that I got this error and then it disappeared. When I loaded up GW today it was back and it's everywhere. From the moment the game starts all the text is blurry.
I've attached an image to give you an idea.
Also noticed this when in my guild hall.
Notice the haze on the left side of my avatar?
