To reproduce:
1. Open attached Unity project "LineRenderer.zip"
2. Open "test" scene
3. Observe GameObject

Expected result: The object should behave and look the same from every angle
Actual result: The object gets corrupted and changes its appearance when observing it from every side (see attached gif "LineRendererbug.gif")

Reproduced on: 5.5.3p4, 5.6.1p2, 2017.1.0b7, 2017.2.0a1

Note: The Line Renderer only breaks if some of the elements are too close to one another or if the figure generated from the elements' positions is really complex
