Windows UI scaling not respected

[svan]

I don’t use the Windows operating system on a regular basis and therefore cannot answer your question. However, the demo below shows how to scale JavaFX drawing in case that could be a possible work around to the window scaling issue. The circles start out the same size, but only the first one is scaled up.

import javafx.stage.Stage;
import javafx.scene.layout.Pane;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.transform.Scale;

void setup() {
  size(1, 1, FX2D);
  Stage stage = new Stage();
  Pane pane = new Pane(); 
  
// Circles start out the same size.
  Circle circle1 = new Circle(200, 155, 50);
  circle1.setFill(Color.BLUE);
  pane.getChildren().add(circle1);
  
  Circle circle2 = new Circle(450, 155, 50);
  circle2.setFill(Color.RED);
  pane.getChildren().add(circle2);
  
// Only circle1 is scaled.
  Scale scale = new Scale();
  scale.setX(2.5);
  scale.setY(2.5);
  scale.setPivotX(200); // Same as original coordinates
  scale.setPivotY(155);
  circle1.getTransforms().addAll(scale);

  Scene scene = new Scene(pane, 600, 350);
  stage.setTitle("Scaling transformation example JavaFX");
  stage.setScene(scene);
  stage.show();
}
