Using Shader Model 5 and tessellation on Linux gives strange results that are not present when used on Windows
1) When using Shader Model 5 on Linux, turning on Translucent blend mode and Tessellation causes the material preview to flicker.
2) Lit material with tessellation does not cast shadows from dynamic world light (sun)
Material preview begins to flicker wildly.
