Try this sample, I chucked it together from code I had (so it isn't well documented and you need to fix package name et c) but it works.

Edit: oh and you probably need to fix the version line in the shader, I'm on Mac which only supports OpenGL 4.1

I tried your sample and it seems to work just fine 'as is'. I've uploaded a picture of the output while it runs here for confirmation:




The code also works after changing the shaders to use version 440 from 410. I did, however, notice that when you exit, an exception is thrown and a significant amount of output is produced.

Thanks for the help. I'm including the console output during its last moments below, triggered by closing the window.

EDIT: The application works regardless of whether the -Dsun.java2d.d3d=false argument is sent to the JVM or not. I expected this to be the case at least under GNU/Linux.
