Citroen C3 WRC front window reflection bug

I have this same issue, it's not just at night either. It's bad in Monte during the day, the windscreen reflects the snow on the road and you can't see a thing cause it's just flashing white reflections over like 70% of the screen. I suspect the floor of the car or something like that may be transparent and letting light through that it shouldn't. It's a shame, cause I absolutely love the car otherwise!
