Java test case.

I'm a developper of the Scilab software. Many of our users have experienced issues using the JOGL API (https://jogl.dev.java.net/)
on all the Intel graphic cards (such as i810) under Linux using Intel drivers (it's ok if they install the mesa ones).

Basically JOGL provides a Java wrapping of OpenGL and Java components which provides OpenGL rendering support. There are two of these components one for the AWT API one for the Swing API. The second is not working with these cards.

After some investigation, I found that the Swing components is using
pbuffers. I then guess that pbuffer support is buggy with current drivers and then prevent JOGL to work.

To test the problem, you may try to run the JRefract demo from the JOGL
website (https://jogl-demos.dev.java.net/). I also
created a small test case (in attachment), but you will need to get the
JOGL API before installing it. Personally  I use  the 1.1.1 version
You can try it as if or fully accelerated using the
"-Dsun.java2d.opengl=True**" option.

I don't have a computer with an Intel card right now, but I will soon be able to use one. I will then be able to perform some more tests to be able to help you.

pbuffers are not supported in any existing release of our driver (or any open-source driver, that I know of).

We're including EXT_framebuffer_object support in this quarterly release, and if JOGL chose to replace pbuffer usage with the newer (better) extension, it would work on our driver.

So I'm marking this as won't fix.

Thanks for your quick reply. I will report the information to the JOGL's developers.
