i'm trying to do a very simple OpenGL preview, but for some reason am getting strange errors. below is the patch and the errors i'm seeing.

when i load the patch below and load a video i keep getting the following error.

jit.gl.texture: error disabling texture unit: GL Error: Invalid Framebuffer Operation

any ideas what might be happening here? this is on a latest 15" retina macbook pro. macos with nvidia graphics. OpenGL info at the bottom of this post.

i would recommend a slight modification to your setup. what you're doing is sending a gl_texture directly to jit.pwindow. this causes the pwindow to convert the gl_texture to a matrix via a CPU readback, and this can be inefficient. instead simply create a shared context using the jit.pwindow.
