Greetings jarscr,
Welcome to the Apple Support Communities!
I understand that you are seeing a flickering bar on your MacBook Pro. In this situation, I would recommend reading over and working through the troubleshooting steps in the No video or no signal, image distortion, "snow," or flickering section in the attached article.
