I have been getting jit.gl messages and spent hours, if not days trying to figure out why... finally narrowed down to where I see the same errors running jit.gl.syphonserver
example receiving from jit.gl.syphonclient
example patch, please see screenshot. I'm hoping to clear this error, running Max 7.3.5 on Macbook Pro 13.
jit.gl.videoplane: jit.gl.texture: error disabling texture unit: GL Error: Invalid Framebuffer Operation
jit.gl.texture: error disabling transform: GL Error: Stack underflow
jit.gl.render: erase: GL Error: Invalid Framebuffer Operation
