When the Title property is set to "" the RibbonView displays the ApplicationName two times. If the Title is set to null via binding the control displays the ApplicationName three times. The problem doesn't occur when the RadRibbonView is hosted in a vanilla Window.
Application title disappears when you change the current theme to Expression_Dark or Windows8. As a workaround: You can set the RadRibbonWindow.IsWindowsThemeEnabled static property to False in order to apply the Telerik predefined themes instead of using the Windows OS theme.

The app starts with the backstage open (IsBackstageOpen="true" for RadRibbonView).

In WPF the WindowsFormsHost control is displayed on top of the Backstage menu Reason for declining: The WindowsFormsHost element is drawn on top of any Adorner elements. As the RadRibbonBackstage is an Adorner the WindowsFormsHost is drawn on top of it. As a workaround to this framework limitation you could bind Visibility of the WindowsFormsHost to the IsBackstageOpen property of the RadRibbonView and collapse/hide it when the backstage is open. You can find more information about the WindowsFormsHost and its features and limitation in this article ( http://msdn.microsoft.com/en-us/library/ms744952.aspx ).
When you have a RibbonView in a RibbonWindow and you open another RibbonWindow from the first one, the paths of the minimize, maximize and close buttons of the first window disappears. Note that in order to reproduce this issue the Windows theme should be set to classic and the project should be started without debugging (Ctrl + F5)
When RadRibbonView is hosted in RadRibbonWindow and the window is moved partially outside of the visual area of the screen the tabs' minimized content is misplaced.
TreeView or DataGrid, or COmbobox is placed in a dropcontent of a RibbonDropDownButton. Item is selected programmatically before the dropdown is loaded. This leads to null reference exception.
When we have a RibbonWindow with the Office2013 theme applied and palette set to (for example) LightGray the background of the window is not changed.
When the Windows OS theme is changed to Classic under Windows 7, the Minimize, Maximize and the Close button of the RadRibbonWindow disappear and the title bar becomes black.
