I'm using vr if that matters. How can I avoid this, it's been going on for years now and seemingly random. I left the lobby and changed cars.
We've found that this only happens to the 3rd person to join the server. If you are not in VR they are completely grey like the active reflection skin/window/whatever is missing. It seems to only happen in Practice/Qualifying and works fine in Race (Not 100% sure on this part).
