Blank display on macOS

[Nicd]

macOS 10.14.3, Elixir 1.8.1 on Erlang 21. I only see a black screen and the fractal is not drawn.

Anything I should try?

Sorry, just seeing this now because I had my notifications configured wrong. Likely due to something about the Intel HD Graphics OpenCL implementation. I believe I have a laptop with this configuration so I'll check this weekend.
