Hi Everyone,  
I m trying to develop a cylinder rolling game for mobile platforms. I have a problem with the rolling cylinder on a straight floor. It is bouncing when it moves for a while. There is no collision problem or protrusion, the ridge on the surface. You can check the screen record gif to understand clearly.
