Cars - Holden #10 Racing Team Commodore VF 2013 - Wipers or windshield itself is bugged

Just check the video to see what I mean. There are these weird large white spots on the windshield that just don’t go away. Race was set to “Evening” and the weather is “Rainstorm” if that matters.
Please fix the bug, because ppl that want to play in cockpit view will barely be able to see anything during the rain.
