    I'm still able to reproduce this though the linked issue is mentioned to be resolved.
    I'm getting this :

    OpenCL Error. Falling back to CPU lightmapper. Error callback from context: [CL_INVALID_KERNEL_ARGS] : OpenCL Error : clEnqueueNDRangeKernel failed: kernel_arg 3 has not yet been initialized
