Hi @Aryszin,

In Windows, the title bar can be customized using the Windows API in C#: [Title bar customization - Windows apps | Microsoft Learn](https://learn.microsoft.com/en-us/windows/apps/develop/title-bar?tabs=wasdk)

You can access the [`java.awt.Frame`](https://docs.oracle.com/javase/7/docs/api/java/awt/Frame.html) instance like this and modify it’s shape for example (you can make it transparent [here](https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/uiswing/examples/misc/ShapedWindowDemoProject/src/misc/ShapedWindowDemo.java)) :

```processing
import processing.awt.PSurfaceAWT;
import java.awt.Frame;
import java.awt.geom.Ellipse2D;

void setup() {
  size(500, 500);
  
  PSurfaceAWT.SmoothCanvas canvas = (PSurfaceAWT.SmoothCanvas)(surface.getNative());
  Frame frame = canvas.getFrame();
  
  frame.removeNotify();
  frame.setUndecorated(true);
  frame.setShape(new Ellipse2D.Double(0, 0, width, height));
  frame.addNotify();
}

```

But I don’t know if the Java API can access and modify the style of the title bar. You might want to investigate more:
