MahApps integration theme switch not working properly

Hello, I have the standard App.XAML integration code, section “The App.XAML”: https://github.com/MaterialDesignInXAML/MaterialDesignInXamlToolkit/wiki/MahApps.Metro-integration

I change the theme using this code: public void SwitchTheme(bool IsDark, string SelectedPrimaryColor, string SelectedSecondaryColor) { IBaseTheme baseTheme = IsDark == true ? Theme.Dark : Theme.Light; Color pColor =(Color)ColorConverter.ConvertFromString(SelectedPrimaryColor); Color sColor = (Color)ColorConverter.ConvertFromString(SelectedSecondaryColor); ITheme theme = Theme.Create(baseTheme, pColor, sColor); ResourceDictionaryExtensions.SetTheme(Application.Current.Resources, theme); } But theme doesn’t change properly, obtaining a partial switch like this:

Am I doing something wrong or is this a bug? In another app it works fine. Thank you in advance for any help!

Please check yourself. I prepared a very small app reproducing the issue: MaterialDesignXAML.zip

Thank you very much for your attention and help. It seems it works now perfectly both in demo app and final app. Also, it’s more lightweight and straightforward code too: excellent improvement. I strongly suggest you to update the Wiki (as you did for issue #1325) since it seems was only a bad Wiki old code reference and not a true issue. Updating Wiki will prevent other users from encountering the same issue.

I’m closing this because the issue has been resolved. Thank you again.
