It offers a temporary fix. https://www.mediafire.com/?2u02pwotxi15f2x Also, If you have an issue with the "A Button" bringing up the hidden overlay menu make sure you have "Apps can add a border" enabled. You can do this by navigating to settings -> Display -> Video Settings -> Tick the box that says apps can add a border and your set.
