Hi, I have encountered severe lag in my application when resizing the stage while an animation is running. I've made this very simple example code to reproduce the issue: https://github.com/Drakkoon/LWJGL-FX/blob/master/src/JavaFXResizeTest.java This is only a tread that acquires a semaphore, prints the System.nanotime() delta and releases the semaphore. There's a button on the stage that can clicked on to start a fade animation and stop it. Resizing the stage while it is animating will create huge deltas in the thread. Stopping the animation brings everything back to normal. Restarting the animation once resized and stopped does not create the huge deltas until you resize again. Does anyone know what is at play here, what underlying system creates the lag and how to avoid this? Thanks.
