Qt's map hadn't been updated to draw unexplored locations with the unexplored glyph so was still using solid stone instead. Column 0 should be removed but I'll leave that for someone more adventurous; I did it for curses and for X11 but am going to pass here. It's very noticable after magic mapping but is only "bad" (by wasting space) if clipping is being performed.
