I have experimented with blurred window backgrounds as well as blur-behind materials within the JavaFX scene graph.
Here's a screenshot of a JavaFX application using the effect that you probably want: https://user-images.githubusercontent.com/43553916/216404144-da1cb463-c650-4fc3-ae05-e2b21385d66b.png I've implemented this effect for the Windows toolkit using DirectComposition. Other platforms need their own implementations. Blur-behind materials within JavaFX scene graph can be implemented in a platform-independent way. My solution would extend the effect infrastructure by adding a `Node.backdropEffect` property, which complements the existing `Node.effect` property. `Node.backdropEffect` works similiarly to CSS's `backdrop-filter` (see https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter). This is how you would use the backdrop effect: var rect = new Rectangle(); rect.setBackdropEffect(new GaussianBlur()); // looks like a colorless sheet of glass rect.setFill(Color.TRANSPARENT); // looks like a red sheet of glass rect.setFill(Color.web("red", 0.5)); Maybe that could be a useful feature.
