If you place a TextBlock in the QuickAccessToolbar and the Ofice_Black theme is applied you get black foreground on black background which makes the text unreadable. The content of the QAT must respect the theme applied to the RadRibbonView control.

In application Menu, when hovering the dropdownbutton to open the RightPane, clicking an item in the Pane does not closes the application menu

RibbonBar should set default GroupNames of the RadRadIoButtons used

I assume that even though this is listed under RadControls for Silverlight it will also apply to RadControls for WPF.

When RoutedCommand is used in RadRibbonBackasteItem the OriginalSource is wrong.

In SL this scenario is only in OOB mode, with BorderlessRoundCorners.

When Windows Classic theme is applied in Windows7 ( or when XP is used) and the WindowStyle of the RadRibbonWindow is set to SingleBorderWindow, the scrollviewer in the backstage does not work properly

We have a RadRibbonView with enabled KeyTips and a RadComboBox control below it.
We focus the RadComboBox and press "Alt + DownArrow". As a result the the RadComboBox is opened and immediately closed and KeyTip is activated and shown and the coressponding RadRibbonTab gets the focus. The expected result is that the RadComboBox is opened, remains opened and no KeyTips are activated.

When the DropDownButton in an ApplicationMenu is clicked, the DropDown area should not be closed (see MS Excel for reference).

RibbonGroup collection can be populated only w/ buttons from the designer

If you delay adding a RibbonView in a RibbonWindow, the RibbonView is placed on top of the window, hiding its TitleBar.

When both Command and IsEnabled of RadRibbonBackstage are bound, the Command has Higher priority. This is inconsistency with the behavior of Buttons and RadButtons. The RadRibbonBackStageItems should work like RadButtons.

The KeyTips of RadMenuItems go behind the menu when hovering over the RadMenuItem. This issue seems to be related to the ScreenTip/ToolTip settings applied on the RadMenuItems - if no such settings are applied, the issue cannot be reproduced.
The Tooltip popup is placed over the KeyTips popup.

RadGallery is used in RadRibbonView  and ListBox under the RibbonView with  DeferredScrollingEnabled set to true. When scrolling the Gallery, the ListBox Scrolls unexpectedly.

If a RibbonView is used in a WPF, where the Window SizeToContent property is set to WidthAndHeight, the Window takes too much space.

There are three errors for missing icons when implicit themes are used:
Resource '/Telerik.Windows.Controls.RibbonView;component/HelpIcon.png' was not found.
Resource '/Telerik.Windows.Controls.RibbonView;component/RibbonGalleryCollapsedIcon.png' was not f

There is a flickering when the active ContextualGroup is changed - the RibbonView first selects the non-contextual main tab before it switches to the according contextual tab. The flickering can't be observed every time.

Open the Application menu.
Open one of its submenus.
Hover another button.

The opened submenu will not close.

This issue occurs when the ApplicationMenu is bound. The button in the ItemTemplate of the ApplicationMenu could be both RadSplitButton and RadDropDownButton. Their DropDownContent should not be displayed downwards, it should be displayed in the RightPane ( the Content of the Applicationmenu)

Declined: When the ApplicationMenu is in DataBound scenario the ItemsControl from which the ApplicationMenu inherits automatically creates ContentPresenters for each item and wraps their content. As the ApplicationMenu knows how to manage RadRibbonDropDown/Split buttons you will need to provide one of these containers as direct child of the  menu. You can achieve that using the following code, to show all items as RadRibbonDropDownButton:

public class CustomApplicationMenu : ApplicationMenu
    {
        protected override bool IsItemItsOwnContainerOverride(object item)
        {
            return false;
        }

        protected override DependencyObject GetContainerForItemOverride()
        {
            return new RadRibbonDropDownButton();
        }
    }
