Ship models have holes

After Sins Rebellion finally released, some ship models have started to show some holes and this happens usually at the beginning of the game after a while they disappear, even changing the graphic settings didn't make them disappear, here's some screenshots:

I don't know if it's because of the newly installed graphic card driver or if it's a real bug, I still have the save of the game when they appeared if the devs need it.
