Short description of error
Blender 2.78a has an issue where one can see some wireframe z fighting only when matcap shading is enabled.
Exact steps for others to reproduce the error
1 - default cube scene
2 - Add sphere
3 - Subdivide N amounts
4 - Apply smooth shading
5 - Enable any matcap
6 - profit of the limited bug ;)
