Gluonfx编译iOS应用旋转屏幕时崩溃问题求助

我使用GraalVM将Gluon应用编译为iOS应用，部署至多款iPhone和iPad设备。该应用需每秒更新数次图片，初始启动未更新图片时屏幕旋转正常，但首次更新图片后，旋转屏幕（尤其在iPhone设备上）会导致Gluonfx框架崩溃并重启。

问题细节 #

• 应用展示的图片尺寸较大，支持平移和缩放查看细节
• 在iPad 10代上几乎不会崩溃，但在iPhone 14 Pro上必然触发崩溃，推测与屏幕尺寸相关
• 已尝试的排查手段：重组代码、移除视图、放慢更新速度排查竞态条件、单步调试视图更新，均未解决问题
• iOS模拟器中无法复现该问题，但视图更新速度极慢（使用Platform.runLater更新需约2秒，而真机及PC端纯JavaFX环境下仅需不到10ms）
• 已跟踪内存使用情况，JVM在所有设备上表现一致
