Was not easy for me to realize what you were asking about. That gray mortar
is very obscure, making it difficult to see.
What's happening is that the default antialiasing cannot discern such fine
lined patterns. Also that the rays being traced eventually have a limitation
at a small scale. What you can do to improve it is use more ray depth, +r4
or more will help. And you should probably use +a0.2 or less too. Read the
documentation section on antialiasing, 5.2.6.4 Anti-aliasing Options for
more concise information.

0.3, that is not antialiasing, that is test rendering :)
I use +aa0.01 +r6 when I do brick buildings, and I get some moire anyway.

To get the best antialiasing, use "+a0.0 +am2".
This is, naturally, quite slow. For a bit less-quality but faster
antialiasing use something like "+a0.1 +am2".
