Does not help.

I think the problem is that FX stage is being manipulated from the EDT, see the comment  in JFXPanel:607 and the FX stage access on JFXPanel:640.  

You probably need to wrap the following code in Platform.runLater(), though I can't tell if sendResizeEventToFX(); should be in the EDT or FX app thread:


            if (stage != null) {
               stage.setRenderScaleX(scaleFactorX);
               stage.setRenderScaleY(scaleFactorY);
            }
            sendResizeEventToFX();
