Repainting a dirty region interfere with graphics2D clipbounds

Question

In the following reproducer, I am reproducing what I'm seeing in the graphical interface. I'd like to repaint a dirty region of a canvas (a JPanel), because a full repaint introduces more latencies.

However when the repaint (dirty rectangle) function is invoked, it causes some issues with nested Graphics2D objects. In particular

This code may mis-use clip bounds, but I wasn't expecting this "artifact" upon the creation of the sub (nested) graphic context.

What would be the proper way to deal with clips, nested graphic contexts, and the dirty region (or rectangle) repaint in this situation.

My intuition tells me the code should compute its shape without using the clipping area.

        var comp = new MyJPanel();
        var timer = new Timer(2_000, e -> {
            SwingUtilities.invokeLater(comp::bug);
        });
        timer.start();
        timer.setRepeats(true);

        SwingUtilities.invokeLater(() -> {
            var frame = new JFrame("Reproducer");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setSize(new Dimension(300, 300));
            frame.setVisible(true);
            frame.getContentPane().add(comp);
        });

            var graphicsBox = (Graphics2D) g2.create(10, 10, 290, 290);
            var clipBounds = graphicsBox.getClipBounds();

            graphicsBox.fill(new Rectangle2D.Double(clipBounds.x + 2,
                                                    clipBounds.y + 2,
                                                    clipBounds.width - 2,
                                                    clipBounds.height - 2));

            graphicsOverlay.dispose();
        }

        public void bug() {
            getVisibleRect();
            repaint(100, 100, 100, 100);
        }
    }

EDIT by moving the fill above drawRect
