I think it might has something to do with Z-Sorting as the seems are visible in LDCad too, caused by 'double' alpha blending of certain polygons.
LDCad does part level z-sorting, while LDView does polygon level sorting hence no seam.
Don't know how that leaks into ray tracing though, as I thought Z-Sorting was a rasterizer specific thing.
