Hi @Andrey-Kozlov , I'm not sure what you meant by "Picture deforms and white lines appears", is it supposed to not look like this? Can you tell us what you expect to get from the setup and what exactly is wrong? Thanks!

The screenshot provided inside the zip seems to indicate the described bug:

But this isn't really a bug. The provided depth map already comes with these bands:

This is a resolution limit of the texture itself. Not a displacement bug.

@mano-wii I think my previews are too small to reveal those artifacts... If so then likely not a bug

Here is the same scene rendered in Octane Render. The geometry is ok and no white lines

Did you put any reflective material on the Octane Render? Is the lighting really the same?

I got it. White lines was my fault, because of specular material. But horizon line in cycles is still not straight.

Images showing renders with mismatched materials and not even showing any displacement is not enough to reveal a Displacement bug.

The bug report needs to be straight to the point. Otherwise it appears to be a support request for a specific scene and not a bug.
