Both of them have GLCanvases controlled by Animators. Moving one of the windows on the desktop causes a non- recoverable error, a crash with the following trace: net.java.games.jogl.GLException: Error swapping buffers at net.java.games.jogl.impl.windows.WindowsOnscreenGLContext.swapBuffers (WindowsOnscreenGLContext.java:140) at net.java.games.jogl.impl.GLContext.invokeGL(GLContext.java:270) at net.java.games.jogl.GLCanvas.displayImpl(GLCanvas.java:186) at net.java.games.jogl.GLCanvas.display(GLCanvas.java:74) at net.java.games.jogl.Animator$1.run(Animator.java:104) at java.lang.Thread.run(Thread.java:534) An unexpected exception has been detected in native code outside the VM.

The test case works on NVidia hardware. Bug fixes and additional workarounds have recently been checked in to the single-threaded workaround designed for ATI hardware. The attached test case works properly with the code in the CVS repository, which will be introduced in JOGL 1.1 b08. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:46 EDT --- This bug was previously known as _bug_ 90 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=90 The original assignee of this bug does not have an account here.
