Alright . Immediately after I sent this pose , I realized what I've ignored . The problem happens each time I'm writing something into my user-defined buffer. So when the program is writing things into it , there's an error . I discovered this by glCheckFramebufferStatus , which is hidden if there's nothing going to be written into that problem buffer . In this case , I soon replaced it with the default one .
The problem I got is GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT . This is not given by glGetError
