Help find a file

Hello all, can someone give me a hand and tell me what file this box is drawn in http://gyazo.com/9577ca509e5ade9e233f92fb881745c7 I have been looking but cant find the file

That is for the tips part of it when you are spectating, I was making the boxes square and already did that file but there is another file must be that shows you the tips for the role you are when you first start the round. That is the file I am having a hard time finding

Any ideas?
