Problem:
If I want to type something in the address bar, a black stripe appears. If the focus isn't in the address bar, the box disappears.

It is really annoying if I want to type in a URL or edit the URL.

Does someone know, how to solve this problem?

In the screenshot, it doesn't shows the black bar, but in the picture it does.
