Unity scene editor flashing red while playing my scene

Hello,

This starting happening all of a sudden. When I press play, the scene view starts flashing red but the game view is fine. I noticed that this stops if I disable lighting. I’ve checked my lights and they haven’t been touched for the last 2 weeks. Any help is appreciated.

Thanks

Fixed. There was a problem with some background sprites I was using for my parallax background. I had to reinsert them back into the scene…weird…
