To reproduce:
1. Open user's attached project
2. Build and run

Expected: textures are not corrupted (check correct result in Editor's Play mode)
Actual: textures are corrupted/flickering

Reproduced in: 2017.4.6f1, 2018.1.6f1, 2018.2.2b10, 2018.3.0a3

Note1: D3D12Sampler m_Sampler is reported to be the origin of the issue
Note2: other unsafe fields include:
- UInt32 m_BoundStages;
- UInt64 m_TextureStageBindings[D3D12ShaderType::kD3D12ShaderCount];
- UInt32 m_SamplerStageBindings[D3D12ShaderType::kD3D12ShaderCount];
