Is this a build from or did you build it your self? if it's a homebrew build, what version of cuda did you use?

It is official build from

Problem is relevant some builds ago till now (build from Oct 18 2018 00:01:19)

BTW: Same file rendered by CUDA on 2.79b - official build (GPU only) is OK.

@Brecht Van Lommel (brecht), maybe you can check that one?

Problem of render artefacts of GPU seems to disappeared.
I have recognised first correct render results on 6.12.2018 (official beta build Linux64).
Issue can be closed.
