Guild Wars 2

I have ATI Mobility Radeon. I went to the AMD website and found an updated version for my driver. I downloaded it and restarted my computer. When I logged into GW2, everything was working perfectly. Then, I exited to the desktop and came back an hour later to the same problem. It seems like the first time I run GW there are no problems as long as I don’t exit or minimize.

I am having a weird (graphics?) issue. My screen fragments while playing and makes it impossible to see. I did not log in for a while, so after doing a fairly large update, I logged in and saw this. After restarting my computer, it worked fine. After minimizing and re-opening the screen, however, it continued. This also occurs on the login screen and during updates. I tried to adjust the graphics options, but no luck there. I am running Windows 7 OS with 6GB RAM and 2.10 GHz processor if that helps. I am hoping that I do not have to reinstall the game to fix this problem.
