Mine was working just like you described where there is no background but it shows a line with black background every now and then. Now it just went to permanent black background and it's annoying as **bleep**. I wonder how I can go back to what it was before. I had background opacity set to 0 and it was just fine, there has to be a reason why it's acting like this.
