    Hello,

    I working on mac, I create a class inherit QOpenGLWidget, and reimplement
    virtual void initializeGL(), virtual void paintGL(), virtual void resizeGL(int w, int h).

    It's working fine,
    but while I resize the window, the block of gl widget only display black and get these message:
    QOpenGLFramebufferObject: Framebuffer incomplete attachment.
    QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
    QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
    QOpenGLFramebufferObject: Framebuffer incomplete, missing draw buffer.
    QOpenGLFramebufferObject: Framebuffer incomplete, missing attachment.

    I tried to find answer in the Internet, but obviously did not find.
    I'm very grateful for any ideas : )

      Hi and welcome to devnet,

      What version of Qt are you using ? On what version of OS X ?

      Also, can you share your widget's implementation ?
