Extremely ugly borders around xfce4-terminal that wont go away.

xfce4-terminal 1.0.1 results in this happening:

I've tried various things in gtk.css and even just xfce.css and nothing seems to make these go away, I'm not sure what's even putting these here and why they're not disappearing when I explicitly have "Show Window Borders" unchecked.

These borders block mouse clicks and affect window snapping and are captured in screenshots all the time.

Any idea what's making this happen? It's really frustrating.

I just simply want a plain completely borderless terminal window, absolutely no decoration, only the terminal content and nothing else.
