I used this tutorial and made OneTriangle app
It runs fine in many environments except one computer with Intel Atom CPU D525 1.80GHz. CPU Specification:
There are no errors in Java Console.
Expected Behaviour: Window with 3-color triangle and black background.
Actual Behaviour: A window with transparent background without the triangle. Looks like drawing surface is not initialized.
I tried to launch the app from command line in the same environment and it works like a charm. The bug can only be reproduced when app is launched from Java WebStart.
Please provide platform, .. , debug info (wiki/faq/bug report).
You can generate debug info for JNLP via the property settings
as described here http://jogamp.org/wiki/index.php/Jogl_FAQ#Applets_and_Java_Webstart
reduced to 'normal' since it is not confirmed yet ..
btw - can you pls also test w/ one of our latest pre-releases ?
I tested the same app in the same computer using this build
... and it works for me! Thank you very much for your help!
