MacBook Pro rectangle framing
It happens on my macbook pro in some apps to put different buttons into a blue rectangle and it gets really annoying because it starts to fade away, for example on Twitter the back arrow is framed into a rectangle, or in Apple Music the star ratings are framed too. And in many other apps even on Safari it is really frustrating. What should I do? even after a software update it's still there.
