mxao works only when I hover on the close menu button (ts4)

I had sort of given up on trying to make it work but everything works fine in Display Depth. I've noticed it shows up like this just now. 

Nevermind, it fixed itself when I stopped downsampling the game. I don't know if that was the problem but at least it's solved.

did your mxao turn off and on if so how did you fix that problem
