Feel free to move this thread to bug reporting, as I'm unable to post there...

From the latest source distribution I got the exception below. Not sure how to reproduce the error. This is a severe bug, as it causes any application to crash without the ability to work around or catch the exception.

Code:

I can confirm the crash and I am able to reproduce it: Take another window and move it over the window containing the xith3d canvas. After a cuple of flickerings the application will crash. Same will happen when moving the xith3d window a cuple of times.

my setup:

• Windows XP SP3
• GeForce 6800
• NVidia Driver Version 257.21
• Java Version 1.6.0_20

Yet another confirmation.

Setup is Windows 7-64 Pro, GTX 260, driver version 191.07, java 1.6.0_17.
I'm using the JOGL interface for my app, and the renderloop is in RUN_SEPARATE_THREAD.

The exception occurred when switching to another pane in a tabbed application, and back; this does not always cause a crash. Moving another window (external application) over the viewport and moving it around or leaving it does not seem to cause a crash.

Stack trace is similar to previous posts:
