Guild Wars 2

I was walking around black citadel when I noticed this, when I approached the laurel merchant near Diessa Gate Waypoint , half of the world started disappearing & reappearing, including my character. I’ll include a screenshot about the location . This doesn’t happen anywhere else just at this specific area

Also a screenshot with the disappearings

Make sure your video card software has anti-aliasing set to either off or use application settings.
