This is reproducible with javafx 1.0.1 b02 on desktop. This works fine on mobile.

I'm showing a Rectangle with strokeDashArray set to [1.0] which is its default value. This shows a difference in the appearance of Rectangle's stroke - it looks as if stroke is broken at some points. To reproduce, run the below code.

import javafx.scene.*;
import javafx.stage.*;
import javafx.scene.shape.*;
import javafx.scene.paint.*;

Stage {
    scene: Scene {
        content: Rectangle {
            width: 80
            height: 60
            x: 40
            y: 40
            fill: Color.BLUE
            stroke: Color.RED
            strokeWidth: 20
            strokeDashArray: [1.0]
        }
    }
    width: 200
    height: 200
}
