I get this strange distortion from time to time as shown in this picture. It moves to some degree depending on the angle I’m looking from, and obviously this can be more than a little distracting. Am I doing something wrong? In this example, this is a very early stage of a landscape, all I have done is lay a plane, subdivide it, and set the fractal to .7. I don’t feel that I have done anything unusual, though I’m very new to blender so I might be missing something.
Any help will be appreciated as I get this from time to time.
