How do I create proper background loop ?

Hi,

I have created the background loop, I Used *dt delta time) for moving the sprite.

The background is looping properly, but in between some line have blinked when background moving.

if not using *dt (delta time) that line not blink.

Actually my game was slowing down after some time when playing, that's why I am finding the solution.

please let me know if anyone have solution.
