This is a small modification for the instant replay overlay, intended to be a workaround for the issue of the "hide overlay" button remaining on the screen and thus spoiling the ability to take good screenshots. By replacing the highlighted/mouseover texture for the button with a transparent one, the "hide overlay" button will effectively disappear when you hover the mouse over it.
With this fix in place, simply position the camera to your satisfaction, click the "hide overlay" button to get rid of the overlay, and keep your mouse pointer positioned over the "hide overlay" button to ensure that it remains hidden. Then press F12 capture a screenshot.
