Seems like a macOS limitation we're hitting with sfml2 here:

https://github.com/SFML/SFML/blob/bd479c4454c0322f60386e5644495400703e41f3/src/SFML/Window/OSX/SFViewController.mm#L243-L261

which means we can not handle events in the worker thread here. We could work around that by scanning in the worker thread and doing all event polling and rendering in the main thread.
