ios - Gluon/JavaFXPorts を使用した iOS でのレンダリング例外

Question

iOS で Gluon を使っていくつかのアプリを試したところ、レンダリングのバグに気付きました。まず、JavaFXLineChartが正しく動作しません。線がずれて、影が正しく表示されません。これ以上は調べませんでしたが、これは次の問題に関連している可能性があります。

さらに重要なことは、Gluon デモ アプリのレンダリング中に という例外が発生することですDoodleTrace。線を描いた後 (iPad では約 20cm の長さ)、レンダリングで例外が発生します。スレッド:
(注: iOS 7 を実行している iPad 3)

1 回トリガー (約 20 cm 後):
