apple.awt.brushMetalLook weird behaviour on mac 10.7 retina

Question

I'm using a 10.7.4 Retina. My JFrame doesn't look as expected when I'm using getRootPane().putClientProperty("apple.awt.brushMetalLook", true);
I tried running it on the JVM 1.6.0_51. It will look like this:

Even tried it with -d32 and -d64.

And when I'm running it on the latest JVM 1.7.0_25 it will look like this:

Both doesn't look like as they should when I'm running it on JVM 1.6.0_15 on a 10.6 mac:

Is there a way to solve this problem? Might the retina resolution be the cause? This post is kinda related to this one in asked before: JFrame is lagging on resize

Answer 1

Yes, you can solve this problem by putting the client property as early as possible.

The Documentation says:

WARNING: This property must be set before the heavyweight peer for the Window is created. Once addNotify() has been called on the component, causing creation of the heavyweight peer, changing this property has no effect.

Here is a MWE:

import javax.swing.JFrame;

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Hello World");
        frame.getRootPane().putClientProperty("apple.awt.brushMetalLook", Boolean.TRUE);
        frame.setSize(400, 300);
        frame.setVisible(true);
    }
}

If you swap frame.setVisible(true); and the part where we put the client property, you get a black frame (Mac OS 10.9.4, Java 1.8.0_05):

Hope, that helped you.
