So, anytime I take a /dump, I get a 6 kilobyte image of a black screen.

any idea whats going on?

There's an issue with the DirectX 11 version not properly generating a screenshot when anti-aliasing is enabled. A fix will be in the next update.

oh, sweet. I kinda thought I was just doing something wrong. good to know otherwise.
