Remove Grid Squares from Header Image?

The header image on our front page shows up with this grid of orange squares all across it that grow when you zoom into the page. We would prefer a clean look without the grid. Is there any way we can disable this option or remove the grid overlay? Thanks for your help


I can’t see any orange squares. What browser are you using? Can you get a screenshot?


There is an option in Customizer > Welcome Area to disable the overlay. But, like Charlie said, I’m also curious in what browser you’re seeing this?
