I think I have tracked down the cause of this problem. It seems to be an overflow in the computation of std::numeric_limits<Temporal::Beats>::max(), which results in the notes moving a huge distance to the left and therefore seeming to disappear. I have submitted a fix on GitHub, but it requires changes in order to be accepted. I am currently working on it.
