Why SwapChainBackgroundPanel and XAML interop happen flashing?

    Question

  • I have a problem about XAML and SwapChainBackgroundPanel interoperability.
    SwapChainBackgroundPanel is the root XAML element, Overlaying Metro style XAML UI onto SwapChainBackgroundPanel.
    Metro style XAML UI were redrew when show a tooltip in XAML UI or Combobox Selected and so on.
    XAML UI has a little flashing.

    I found the issue in Direct2D lighting effects sample.
    How to workaround the issue who help me?
    Thanks very much!

  • You're likely running into a known issue in the Consumer Preview that causes this to happen on some hardware.  This can happen whenever you open/close a Popup control (which include tooltips and ComboBox dropdowns).  Unfortunately the only workaround for the Consumer Preview is to avoid Popup controls.
