I've looked a bit through the JavaFX bugs, and I noticed that many problems involving `synchronizeSceneNodes` are caused by modifying the SceneGraph outside the FX thread which would sometimes throw `ConcurrentModificationException`. As you see this problem only occasionally, it's a pretty good fit. It might be worthwhile to check your logs for such an exception (or similar, like `IndexOutOfBoundsException`). ------------- PR Comment: https://git.openjdk.org/jfx/pull/1123#issuecomment-1535874797
