LWJGL-FX Animations + resize = performance loss

I'm wondering if you have any idea what is causing this massive performance drop when there is a JavaFX transition running and we resize the window. Once resized, if the animation is stopped and started again everything is fine.

I forked and added a button that you can click to start and stop an animation on it so you can see for yourself. https://github.com/Drakkoon/LWJGL-FX

I'm pretty sure there's some caching done on JavaFX's side, but I can't find what, where and how it is affecting this.

Does the performance drop go away if you remove the WebView?

I reduced the example to one of its simplest forms. Just a thread that acquires a lock, and releases it in a Platform.runLater.

I think it has more to do with the pulse thread slowing down the platform's tread pool than the actual OpenGL rendering or ImageView. I might ask about this in the JavaFX mailing list in that case.
