Weird Splotches

I’m having this weird problem where when I sit in a vehicle, sometimes (not everytime, which is weird) white and yellow splotches blossom out onto my screen until it’s completely covered, and then turns my whole screen black, and then my game exits out. Does anyone know why this is happening? Thanks a lot =)

What vehicle? Is it custom, or are you using the jeep/jalopy/airboat?

It’s actually the seats. My bad =P The airboat and jeep seat keep messing up, but it looks like the vehicles themselves are fine. At least, they haven’t messed up YET.
