Rotating images: Poor performance and incorrect direction of the dropshadow

Question

I've created an extremely simple application that is rotating a bitmap image. I have two issues:
1) The performance is quite frankly terrible with stuttering and screen tearing. Is there any way to improve the performance or is this a known limitation of JFX's rendering?
2) The Image has a dropshadow, but as the image rotates so does the shadow which is not the behavior I want since that makes it look like the lightsource is also moving. How can I get around this? I want the shadow to stay on the bottom right. Am I putting the dropshadow in the wrong location in the scenegraph?
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import javafx.scene.effect.*;
import javafx.scene.image.ImageView;
import javafx.scene.image.Image;
import javafx.animation.Interpolator;
import javafx.animation.Timeline;
var x: Number;
Timeline {
    repeatCount: Timeline.INDEFINITE
    autoReverse: true
    keyFrames: [
         at (0s) {x => 0.0},
         at (5s) {x => 365.0 tween Interpolator.LINEAR}
}.play();
Stage {
    title: "Application title"
    width: 800
    height: 1000
    scene: Scene {
        content: [
            ImageView {
                image: Image {
                    url: "{__DIR__}image.jpg"
                effect: DropShadow {
                    offsetX: 5
                    offsetY: 5
                translateX: 10
                translateY: 10
                rotate: bind x
}

Answer 1

lol, nope, that still won't show the image... i guess i have really screwed up my install on this system. i had nb6.5 beta then i installed the new nb for javafx but it created an new instance of the app instead of updating the old one. so i removed both and installed the new one... think i will try and setup the nb on a totally clean system and open the app from there and recompile to see if somethin hinky is going on with that.
