I am having a problem with my netflix playing on safari,Showing the error:" Whoops, something went wrong... Display Error : There appears to be a display problem. Please ensure your monitor is HDCP compliant and is not mirrored using Airplay."

While I am not using any external displays and also the airplay is switched off.

Since having this problem , I also noticed an icon on the top right corner of display which i can see when i am logging into my account otherwise not.As i marked the icon by red circle on this picture and i am trying to remove it but I can't . Is there anyone who can help me out. It is Macbook pro with retina display 13''. Thanks
