FBO is framebuffer object, a feature of OpenGL, which Core Image is using under the hood. The status is GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT. Due to the problem using an FBO, Core Image has switched (fallen back) to using a PBuffer (pixel buffer), an old, deprecated feature of OpenGL, instead.
I'm afraid I don't know why using an FBO has failed. You might try the mac-opengl or quartz-dev mailing lists. You can also open a bug report with Apple and then open a developer technical support incident with them asking for a workaround for the bug.
