[texture] background scrolling feels shaky / shaking

[lmezg]

When scrolling the background with the method in this example https://www.raylib.com/examples/textures/loader.html?name=textures_background_scrolling

if you stare at the slow moving background in the back, you will see its shaky. once you noticed it, it's hard to unseen it. I think this is probably due to floating point rounding to integer and we can only shift the background by integers. This is also why fast moving background looks less shaking. I wonder if you have any suggestions on how to eliminate this issue ? (i need to scroll some backgrounds slowly).

This is a good starting place: https://jorenjoestar.github.io/post/pixel_art_filtering/ A better place to ask about these kind of things is raylib discord. Github issues are for a different purpose.

Afaik, it is drawing using float positions so issue could be platform/os/gpu/drivers dependand and impossible to address on raylib side.
