Hi

Please don't call your GLEventListener "GL", it can only cause some confusion. Please provide a SSCCE. Your code demonstrates nothing as you draw nothing in display(GLAutoDrawable). Using AWT on a Raspberry Pi isn't a very good idea, you can use GLReadBufferUtil with TextureData instead of AWTGLReadBufferUtil.
