With the latest Windows SDKs, it is an error to create a multisampled
texture with both bind SRV and DSV flags in feature level 10.0.  The
error:

D3D11 ERROR: ID3D11Device::CreateTexture2D: If the feature level is less
than D3D_FEATURE_LEVEL_10_1, a Texture2D with sample count > 1 cannot have
both D3D11_BIND_DEPTH_STENCIL and D3D11_BIND_SHADER_RESOURCE. This call may
appear to incorrectly return success on older/current D3D runtimes due to
missing validation, despite this debug layer message.
[STATE_CREATION ERROR #99: CREATETEXTURE2D_INVALIDBINDFLAGS]
