Bug 98

---- Reported by bombadil 2004-07-22 11:29:17 ----

Xith applications on my Ati Radeon 9600pro just render the first frame with the 
JOGL binding, then the render loop "hangs". It applies to the Xith demos on 
http://xith.org/demo/com.xith3d.test.php
With my own Xith application not even the first frame is being rendered.

Specifing the -DATI_WORKAROUND=fase parameter makes the Xith apps to work on my 
Radeon 9600pro. However on an Ati Radeon 9800 XL I've seen the same "hang" 
effect with the JOGL version prior to the Ati-Workaround version, both for Xith 
and direct JOGL applications.

Win2000, Ati Radeon 9600pro, Catalyst 4.7 (6.14.10.6458)
Jogl v1.1 beta 04 (2004-07-16)

Hitting Ctrl-Break during the Xith "hang" prints this:
>>>
Hit SPACE to toggle projection policy, or ESC to exit

There isn't an obvious deadlock in the stack trace below, although it isn't
clear how long or why the main thread is sleeping. Can you add some printing
code to see whether the main loop is running properly? Can you also add some
printing code to the underlying GLEventListener.display() routine in Xith3D (or
some similar routine called during every render pass) to see whether the code is
being executed?

This was a race condition between JOGL's automatic discovery that the
ATI_WORKAROUND was needed and the creation of the first GLCanvas and
associated Animator. The need for disabling the setRenderingThread
optimization was computed too late, incorrectly locking out other
threads (in particular, the AWT event queue thread) from performing
rendering of the component.

Fixed by users gkw and kbr.
