Camera lags behind

Hi! I just picked up the game again after it collected dust in my library for a while and I noticed a problem with my camera. Every time I move and the background moves as well, the camera lags behind. I hope you can see in the video that half a second after I stop moving, the screen still moves two pixels to the right or to the left. Is this intended? It makes the game feel really laggy as if it had frame drops.

I hope you understand what I was saying and can help me with this problem.
