If you look at it closely, when you start working, there is a black line on top

Hi,@Eduardo Gomez . I tested your project and there is no black line problem. Is there any other reason?

Hi,@Eduardo Gomez . I downloaded your project and tested it on this machine without the black line problem. If you work on Azure, it is recommended that you file an issue on GitHub.
