I'll postpone till resolve bgfx issue. It crashes unconditionally after configure() for other values too. |

The issue is related to bgfx. I've tried other -video and there it works like a charm |

There is a lingering issue in BGFX where it's mixing up the stride with the width or something along those lines. macOS prints diagnostics to the terminal about it in some cases. |
