here is a screenshot of the artifact i was talking about:
Can you please provide a small self-contained test case?
ok, here is a testcase, that produces the artifacts with RC5:
it seems though, as this only happens with a certain font

yes, it is fixed in RC6. thank you very much!
edit: could the DefaultRenderDelegate class in the TextRender class be made static and public so that we can also use it with mipmapping?
thanks!
edit2: i just tried out mipmapping and after a while the text instantly changed to a very blurry and unreadable version. i couldnt reproduce it yet, but if i can i will post a testcase.
here is a screenshot:
Done. It was not possible to promote 1.1.1-rc6 today, so tomorrow’s build will be 1.1.1-rc6 and will contain this change too.
No ideas, but please post or file a bug if you can come up with a test case.
I just tried moving from jogl 1.1.0 to 1.1.1 under linux. Unfortunately my system (SuSE 10.0 64bit) at work is using glib-2.3.5. Hence does not work. Are there builds agaist other glib versions?
Sorry, not for 64-bit. You can use the 32-bit binaries, which are built against glibc-2.3, with a 32-bit JVM on your system.
i still couldnt reproduce the above artefacts, but it has happened a couple more times since then. all i can say is that it always happened after i have rendered A LOT of text.
JSR-231 1.1.1 release candidate 6 has been released. This release fixes VBO-related issues related to the new TextRenderer, and adds a non-VBO code path for older machines. It also includes an excellent patch from krisher on java.net for longstanding multi-screen issues on X11 platforms. The JNLP extension has been updated:
http://download.java.net/media/jogl/builds/archive/jsr-231-webstart-current/jogl.jnlp
and a stable JNLP extension file for this release has been posted:
http://download.java.net/media/jogl/builds/archive/jsr-231-1.1.1-rc6/webstart/jogl.jnlp
Please try the new release and post if you see any problems.
Please file a bug if you can come up with a consistently reproducible test case.
II got this error message with latest release:

Any idea?

Reason is found: I used the GNU Java Compiler and not Sun’s. >:(
In Eclipse you have to do something more:
- Create a new project (or use an existing
- Add two new paths: lib and native
- Download latest JOGL and extract it
- Copy the *.jar files to lib, *.so|dll to native
- Back in Eclipse hit the F5 key and expand the lib folder
- Add both JARs to the build path (right-click them)
And now comes the important two steps:
- Right-click your OpenGL project, choose Libraries and expand the JRE System Library part
- Click on Native library location, click Edit and chhose the native folder where you have copied the so/dlls to
Rebuild the project and you might be lucky… 
;D
ok , i finally got a testcase for the bug i mentioned above. it took me basicall all of my weekend, cause it is really a weird bug. it seems to be connected to a certain character, namely the dash (ASCII 150). but not the character alone causes the problem, only when it is surrounded by other text and then all successive calls to the textrenderer produce scrambled text.
here is the testcase:
import java.awt.Frame;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class TextTest extends Frame implements GLEventListener {
private static final long serialVersionUID = 1L;
int width, height;
public static void main(String[] args) {
new TextTest();
}
GLCanvas canvas;
TextRenderer tr ;
Animator animator;
public TextTest() {
super("TextTest");
this.setSize(800, 800);
canvas = new GLCanvas();
canvas.addGLEventListener(this);
add(canvas);
animator = new Animator(canvas);
animator.setRunAsFastAsPossible(false);
animator.setPrintExceptions(true);
animator.start();
setVisible(true);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
public void display(GLAutoDrawable drawable) {
GL gl = drawable.getGL();
gl.glClearColor(1,1,1,1);
gl.glClear(GL.GL_COLOR_BUFFER_BIT|GL.GL_DEPTH_BUFFER_BIT);
gl.glMatrixMode(GL.GL_PROJECTION);
gl.glLoadIdentity();
//new GLU().gluPerspective(45f, (float)width/(float)height, 0.1f, 1000f);
gl.glOrtho(0.0, 800, 0.0, 800, -100.0, 100.0);
gl.glMatrixMode(GL.GL_MODELVIEW);
gl.glLoadIdentity();
tr.beginRendering(800,800);
tr.draw( "die Marktwirtschaft. Da regelt sich – angeblich", 16, 32);
tr.draw( "Hello World! This text is scrambled", 16, 16);
tr.endRendering();
}

gl.glLoadIdentity();
}
public void displayChanged(GLAutoDrawable arg0, boolean arg1, boolean arg2) {}
}
Thanks, filed as Issue 326. Note that your dash character is not an ASCII dash but some extended Unicode character, which is probably what is causing the problem (fallback to the full Unicode code path).
thanks Ken. So does the current Textrenderer officially support full Unicode? I would highly encourage this, since the game i am working on, is mainly a chat which relies on a lot of strange characters from different languages. 
Yes, it always has. If there are any (other) issues rendering the full Unicode character set they’re bugs and you should file them.
just to let you guys know, there is currently a problem with the nightlies since last weekend. rendering text results in this exception:

the ascii-dash seems to be fixed however. thanks!
Thanks for the heads up. I fixed this and some other issues under Issue 326. The fixes will be in tomorrow’s nightly build.
That’s thanks to John Burkey.
