    Resize OpenGL Window lags


    I have a simple example that only clears and swaps.

    If I resize the window with the mouse I see a "gap" on the right and/or bottom. If I resize the window really fast then the gap will be bigger.

    How can I remove this effect?

    setup: intel hd3000, windows 8

    Make sure you app is not servicing window erase background events - eg an mfc app will do this by default.
