无法创建多采样帧缓冲区

Question

我正在尝试将大小为1920 X 1080的自定义帧缓冲区转换为大小为800 X 600的默认帧缓冲区。

使用以下选项创建窗口

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
glfwWindowHint(GLFW_FLOATING , GLFW_TRUE);  
glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);
   glfwWindowHint(GLFW_SAMPLES, 4);
GLFWwindow* window = glfwCreateWindow(SCR_WIDTH, SCR_HEIGHT, "Renderer", nullptr, nullptr);   // Create the render window
glEnable(GL_MULTISAMPLE);
glEnable(GL_DEPTH_TEST);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

我首先创建一个纹理对象。

// create a texture object
    glGenTextures(1, &textureMsaaId);
    glBindTexture(GL_TEXTURE_2D_MULTISAMPLE, textureMsaaId);
    glTexImage2DMultisample(GL_TEXTURE_2D_MULTISAMPLE, 4, GL_RGBA8, 1920, 1080, false);
    glBindTexture(GL_TEXTURE_2D_MULTISAMPLE, 0);

创建帧缓冲区

     glGenFramebuffers(1, &fboMsaaId);
     glBindFramebuffer(GL_FRAMEBUFFER, fboMsaaId);
    // create a 4x MSAA renderbuffer object for depthbuffer
    glGenRenderbuffers(1, &rboDepthId);
    glBindRenderbuffer(GL_RENDERBUFFER, rboDepthId);
    glRenderbufferStorageMultisample(GL_RENDERBUFFER, GL_DEPTH_COMPONENT, 4, 1920, 1080);

    // attach msaa  Texture and RBO to FBO attachment points
    glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D_MULTISAMPLE, textureMsaaId, 0);  
    glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboDepthId);
    GLenum status = glCheckFramebufferStatus(GL_FRAMEBUFFER);
    if (status == GL_FRAMEBUFFER_COMPLETE)
        qDebug() << "Frame buffer Completed";
    else
        qDebug() << "Frame buffer NOT Completed";

    glBindFramebuffer(GL_FRAMEBUFFER, 0);

我收到帧缓冲区未完成的错误。

错误是GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT，这是由于渲染缓冲区附件引起的。
