Unable to modify RWStructuredBuffer elements via indirect dispatch of a compute shader when using the Direct3D11 API
Reproduction steps:
1. Open project "dispatch_indirect_bug.zip"
2. Open Scene "TestScene"
3. Enter Play Mode
4. Observe Game view
Expected result: RWStructuredBuffer is modified and Scene's background color is green
Actual result: RWStructuredBuffer is not modified and Scene's background color is red
Reproducible with: 2019.4.36f1, 2021.2.15f1, 2022.1.0b11, 2022.2.0a7
Notes:
- Doesn't happen with OpenGLES3, OpenGLCore, Direct3D12 and Vulkan graphics API

Fixed in: 2022.2.0a9
An indirect argument buffer needs to be given the correct buffer type to work on DX11
i.e. IndirectBuffer = new ComputeBuffer(3, sizeof(int), ComputeBufferType.IndirectArguments);
Although the project script will need changing, we are adding an additional message to indicate when a buffer without the correct flags is used with dispatch indirect
