    Hi. I found that my tessellation shader does not work correctly on multiple platforms.

    Its behaviour is very strange, even same project which is built from different machine makes different result. (maybe shader caching related?)

    There are many combinations of platform and graphics api that makes incorrect results. I reported bug with my shader code and screenshots/device logs as Case 1345451.


    Here is part of the issues:
    * Android Vulkan's depth buffer is broken
    * Tessellation Factor does not be applied correctly on Metal
    * Tessellation shader completetly broken on Mac editor
    * All of platforms which I tested returns SystemInfo.supportsTessellationShaders true
