The same test app works fine with LWJGL2 on Windows.

I’m not sure what ever happened to jme3_lwjgl-ogl.

I can try to fix this. I already created an awful working demo. I’ll get it to somewhat nice shape. Try to get feature parity with the LWJGL 2 one and make a PR. Then at least it is implemented and can be improved upon later.
