Switching to the old peeling implementation did the trick, no more issues and yes I am using remote rendering via pvserver.

I managed to reproduce the problem on a wavelet source (attached state file), try increasing the number of elements if you do not see any artifacts. I have bult Paraview from source on OpenSuse 13.1 but also cross-checked with the Linux binaries from Paraview.org and had same issues. There was no problem with the osmesa-llvm flavor though. I couldn't reproduce this here on arch linux with a newer nVidia driver (367.27), so I'm suspicious that this is a driver bug that's affecting the new depth peeling implementation. Since you're building from source, can you try editing VTK/Rendering/OpenGL2/vtkOpenGLRenderer.cxx, and change line 322 if (dualDepthPeelingSupported) to if (false) in DeviceRenderTranslucentPolygonalGeometry, recompile using the OpenGL2 backend, and let me know if the issue goes away? I suspect it will since both the OpenGL1 backend and OpenGL2 mesa/llvm do not use the new code. I'll put together a patch to force the older peeling implementation via an environment variable to make the work-around easier to apply. Patch is here: https://gitlab.kitware.com/vtk/vtk/merge_requests/1589 By the way, are you running paraview with remote rendering via pvserver? I was just made aware of a similar issue with remote rendering and depth peeling.
