What's Wrong?

When I try to view the context, it completely glitches out and corrupts the screen and the text flickers and stuff and disappears. It's like off the edge of the screen and then when I scroll up it just disappears and I can't scroll back down anymore stuff like that.

What Should Happen?

Something less chaotic.
