Hmm... I don't immediately know what the cause is, but I do have a theory. Could you try the version I put up at https://squarewavejams.itch.io/trash-of-the-titans-test (password: dumpster) and let me know if the issue is still present there?
If it still doesn't work, could you tell me some specs about your macbook? Is it an intel chip or one of the newer apple silicon ones (M1, M2, etc.)?
