null window handle: GDISurface

I sometimes get this error when starting my Java3D app. When this happens the Canvas3D doesn't render anything (remains black). Is there a workaround for this?

Hi

It would help if you could reproduce this problem with JOGL but without Java3D, even sporadically. Do you really request a configuration to perform offscreen rendering? Please indicate which hardware you use.

I doubt I could reproduce this with pure JOGL. It only happens occasionally in my Java3D at random runs.

My graphics card is:
NVIDIA GeForce GTX 1660 Ti
CPU:
Intel i7-3770K

I'm using JCanvas3D which I guess indirectly calls offscreen rendering?

I'm adding JCanvas3D to a JPanel which is added to Javafx panel. Is there a better way to do this?

If you used NewtCanvasJFX, the interaction with OpenJFX / JavaFX would be easier and would use less intermediary classes.

Please can you provide a simple reproducer with Java3D if you think you can't reproduce it without Java3D?

I vaguely remember that Java3D Canvas3D and JCanvas3D do NOT extend GLCanvas and GLJPanel.

Interesting, I didn't know about NewtCanvasJFX.
I will try switching to that to see if that resolves the issue. Thanks

Maybe it can help you to know how to use NewtCanvasJFX:

Looks like NewtCanvasJFX is only for JOGL. There's no equivalent in Java3D yet?

Only Phil can answer.
