CW or CCW triangles ignored by the render engine

Is there any way to ignore the CW or CCW triangles during rendering? Some objects are rendered incorrectly, miscolored triangles appear on the surface instead of the color I set. I attached a photo of it. OSPRay Render

No, there is no backface-culling in OSPRay. The artifacts on the chairs indeed look like z-fighting: are there multiple surfaces overlapping at the same spot (two chairs put in each other)? Maybe also the vertex-normals are too extreme (parallel to the surface). Which material is used? Do the artifacts also appear with the SciVis renderer / OBJ material?
