Calling ComputeBuffer.SetData with ComputeBufferMode.Dynamic does not become visible to the GPU when using D3D11 graphics API
How to reproduce:
1. Open the attached project
2. Make sure the Graphics API is set to Direct3D11
3. Click play
Expected result: The cube should change color
Actual result: The cube remains the same color
Reproducible with: 2019.4.18f1, 2020.2.3f1, 2021.1.0b2, 2021.2.0a3
Could not test with: 2018.4.30f1 (can't select ComputeBufferMode)
Workaround: Use Direct3D12, OpenGLCore, OpenGLES3, or Vulkan graphics API

Resolution Note (2021.2.X):
Immutable buffers should be used. It's a doc and naming bug. Immutable buffer is actually the most mutable of them all. Dynamic buffers are meant only for meshes etc, as they're CPU visible. Users shouldn't need to change the buffer mode at all. The default one works on C# side. We're delaying the doc fix for now.
