Specular highlights glitch / artifacts

Hi there, i’ve got some artifacts, they seem to be related to specular hightlights and are visible only on objects edges.

Screenshot-01: This is how it looks (using a texture and some custom material), quite ugly.
Screenshot-02: This is me trying on a newly created, fresh & empty project (no texture, default cube, default material) (still ugly).

Screenshot-03: And this is how it looks when i:

  1. Disable “Specular Highlights” in material settings.
  2. Change “Rendering Mode” to fade or transparent in material settings.
  3. Turn off “Cast Shadows” in mesh renrerer.
  4. Turn of “Receive Shadows” in mesh renderer.
  5. Turn on “Shader Model 2” emulation in graphics emulation menu.

Either one produce the same result, which is a correct result.

To reproduce with a fresh project i’ve just:

  1. Created new project.
  2. Added a cube with transform scale (10, 1, 10).
  3. Duplicated four times and aligned them with snapping.
  4. And voilà, artifacts.

(Artifacts may be not as clearly visible when light hits from top, so i’ve moved the default directional light for more like a sunset orientation.)

Unity 5.6.1f1, Windows 10, gtx 770, latest nvidia drivers.

Seems like a bug probably.



Bump.

Can someone confirm if this is a bug or it is me doing something wrong?
