When my player and Camera both moves in an endless running game, why the background gets flicker?

I am moving my player and camera with the player and at the same time I want parallax effect in the background. I have around 10 layers for background and when my player runs on the platform, the background gets flicker. :frowning: Please help me how to get out from this strange problem.

Actually I made Sprite Texture Type as Default(Texture 2d) and what I am doing is repeating the textures. Upto few layers it is working great but after that flickering starts. What to do in this regard?
