    Hi everyone. I started using jitter with gl3. But, is not work . When I creat and save that shader, The text below is output on MaxConsole. jit_gl_geometry_draw_buffers: GL Error: Invalid operation
    I can use, if i delete geometry shader in my shader. But, gl3 sample is working with geometry. ex Billbord example.
    What's happened? Anybody knows how I do it? Thanks.
