Sometimes when my wheel feels really awkward and almost broken, I see those white graph every time.
What is the meaning of this white graph? can someone explain?

Usually there's only yellow one, but when I see the white graph, FFB feels broken, especially in tight corner my wheel looses all the force. :(
