Bug 129

---- Reported by snagy 2005-01-11 20:07:01 ----

Doing the following with a GLJPanel I get the GLException that can be found
below.  I actually thought it was a problem with my driver but using a GLCanvas
everything works fine.  I tried with jdk1.5.0,1.5.0_01, 1.4.2_05.
 
GLCapabilities capabilities = new GLCapabilities();
   JPanel panel = GLDrawableFactory.getFactory().createGLJPanel(capabilities);
   
   JFrame frame = new JFrame("OpenGL Test");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   
   frame.setSize(400,400);
   frame.add(panel);
   frame.setVisible(true);

A workaround appears to be to call

setDoubleBuffered(false)

on the GLCapabilities object passed to GLDrawableFactory.createGLJPanel(). This
should be done automatically by the JOGL library if necessary.

We've added a workaround which disables the double-buffering flag in the
GLCapabilities for offscreen surfaces in the fix for Issue 41, so I'm marking
this  as a duplicate of that bug. The fix will be present in JOGL 1.1 b08.
Please reopen this bug or open a new bug if problems persist.


*** This issue has been marked as a duplicate of 41 ***
