It is Mioré. Like you said, it happens when a detail is smaller than a pixel, the engine can’t choose which to show. It is a technical limitation of computer screen resolution, it is not something that can be fixed, only avoided.
Mipmapping usually prevents this when dealing with textures - essentially blurring the texture until the issue doesn’t exist.
If for some reason that is insufficient or impossible then other measures can be taken, like altering the shader over a distance to either increase the spacing of the lines or fade it to a solid color.
