    There's an env variable for enabling support for unsupported opencl implementations for
    Blenders cycles renderer.
    Maybe that is needed for rocm.

      Happen to have any documentation on that env var?

        Probably referring to
        Code:
        CYCLES_OPENCL_SPLIT_KERNEL_TEST=1
        , via https://blender.stackexchange.com/a/7486
