On which platform? Same as https://github.com/juzzlin/DustRacing2D/issues/119 that happens on BSD?

juzzlin commented 3 years ago

I think this particular problem was fixed in ae380b82bfdb89ad4dd96510a69d9057d8029b6a, but then we run into other problems. I cannot reproduce the issue on Linux so that is still open.

This happens on FreeBSD. Will check the mentioned commit tomorrow.
