Unfortunately it is. FXAA is an approximate anti-aliasing solution that's
applied as a post-processing pass over the rendered scene -- since ParaView
often does distributed rendering, this is really the only way we can
reliably get anti-aliasing without introducing major artifacts at processor
boundaries.

Because it's only working with the rendered pixel data (instead of actual
geometric primitives), there are some occasional issues like this one. In
this case, it's detecting the intersections as aliased edges and attempting
to smooth them out, fattening the line near the intersection as a result.

HTH,
