I am not sure you are the right people to ask, but I am working my way down the software chain.

I am using the latest version of java3d, compiled on my machine (that has a NVIDIA graphics board) from maven.
        <jogamp.version>2.3.2</jogamp.version>
        <swt.version>3.8</swt.version>

On a NVIDIA graphics board everything works just fine. On an Intel or AMD board there are weird rendering artifacts. It seems to be that surfaces suddenly become see through. Walls do not hide what is behind them (in some spots), the ground does not hide what is below it (in some spots). Those spots change as the view point changes. Attached is a set of images to illustrate the problems. The problems.txt file describes the problems in each pair of files.

This problem started (as far as I can tell) when we switched to Java 8.0, although that may be a false correlation. I used to use LWJGL and it had the same problem. I was hoping that converting to the modern java3d would fix it.

Any ideas?
