PropertyToID is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'Texture' on game object 'Monitor Board'.
See "Script Serialization" page in the Unity Manual for further details.
UnityEngine.Shader:PropertyToID(String)
uDesktopDuplication.Texture:.ctor() (at Assets/uDesktopDuplication/Scripts/Texture.cs:286)
Unity5.x系だとTexture.csのPropertyToIDで怒られる? StartかAwakeで初期化すれば問題なかった。
