      Is it normal render like this with cycles? I set the GPU only (AMD RX 570). Because, if I use the CPU the render is very slow, even when I use OPENCL. GPU is faster, but the result is this picture. With Eevee or Cycles by CPU, everything runs fine.

      Is there something I can do here, to fix this, or I just set cpu+opencl?

        That sounds like a bug! I would recommend reporting it here: https://developer.blender.org/

          I found the same issue on developer.blender.org. I update the drivers to Adrenalin 21.2.2 and I got a clean render. But, I am unable to work in the viewport shader: rendering. Even when I try to use ctrl+B, to select only a fraction of the viewport, Blender crash. I know now, this is a problem with AMD Drivers. Next time, I will buy a Nvidia GPU.

            I will keep working with the CPU + OpenCL to work on viewport shader: rendering, and when I am done, I will render with GPU Compute.

              Ok, sorry to hear that! Unfortunately Nvidia is just more reliable when it comes to graphics software, even in Maya. Hopefully that won’t have to be the case in the future though.
