Hi there,

I have this demo that works perfectly on linux and mac, but on windows it very strange, here is an example of it, maybe its something easy to fix:

Thanks in Advance

- edit:
one thing that I can notice is that on windows the car original orientation is different from linux/osx, could it be some unitialized var?
