Guild Wars 2

I also have been getting this glitch when I’m a part of a large group and lots of attacks are going off.

My trading post window was working this morning after the servers came up, but now the window is blank again.
Works fine on my laptop with ATI video card and on my roommates nVidia gtx 560.

I have a support ticket in for it since I’ve been having issues with this window since before launch.
