The java.awt.font.TextLayout.getBounds() method returns a box that is
shifted upwards compared to the box that is returned by Sun's official
JRE.

Sample code:

import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.font.FontRenderContext;

import javax.swing.JFrame;

public class SwingBug extends JFrame {

	public static void main(String[] args) {
		new SwingBug().setVisible(true);
	}
	public SwingBug() {
		setTitle("Swing bug");
		setSize(400, 400);
		repaint();

	@Override
	public void paint(Graphics g) {

		graphics.setColor(Color.BLUE);
		graphics.fillRect(0,0,400,400);
		drawString(graphics, "Hello Kitty!", 100, 100);
	}

	public void drawString(

			Font f = new Font("times", 0, 16);
			graphics.setFont(f);
			FontRenderContext fontRendererContext = new FontRenderContext(null, true, true);
			TextLayout textLayout = new TextLayout(string, f, fontRendererContext);
			Rectangle2D rectangleOfText=textLayout.getBounds();
			Rectangle backgroundRectangle=rectangleOfText.getBounds();
			graphics.setColor(new Color(1.0f,1.0f,1.0f,0.5f));

The result of the example code on icedtea6

When generating this screenshot this JRE is used:
$ java -version
java version "1.6.0_0"
IcedTea6 1.3.1 Runtime Environment (build 1.6.0_0-b12)
OpenJDK 64-Bit Server VM (build 1.6.0_0-b12, mixed mode)

This is how Sun JRE renders the same window

With Compiz activated the result is getting more weird

The "dust" on the picture appears when I run the test code with compiz
activated. It is not deterministic but is always different on each run
of the code. The "extra" white rectangle is always the same.

It seems to be video driver problem but other (non Java) programs on the
desktop all work fine and are not affected.

I'm no 2-d expert, but these appear to be the same bug:

swing TextLayout.getBounds() returns shifted bounds
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=227

OpenJDK: vertical text metrics may be significanly different from
those returned by Sun JDK

Bug description:
  using openjdk 6b12-0ubuntu6

  running netbeans 6.1, there are some problems with graphic. Maybe the problem is in rendering fonts.
  Everything is bigger in comparison to sun java.
  Even the UML editor has the same text problems for labels: the label text is not inside the field, as it should be, but under it.
  screenshot for the example
