If you have a RadRibbonTab with two RadRibbonGroups and the RadRibbonView is minimized, the groups will be collapsed even if you set their default variant to Large. Will be available in Q1 2015 Release.
The RadRibbonView executes its KeyTips by executing the Command of the Button and the Invoking its peer. This behavior is inconsistent when a user interacts with the button ( first the Click/Toggle is fired then the command is executed).
The RibbonWindow throws exception for missing brush in Expression_Dark theme (Resource with the Name/Key RibbonWindow_InnerBorder is missing)
RibbonView in SL throws exception when LocalizationManager.UseDynamicLocalization is set to true
The buttons of the RadRibbonWindow are not visible in Office2013. The fill of the paths is the same color as the background.

If you set the Visibility of a RadRibbonTab hosted in a ContextualGroup to Collapsed, a placeholder is visualized, when it shouldn't.
The RibbonGroup displays a white border on mouse over around its Image element when the group is in collapsed state when a Windows8 theme is applied.
The RibbonView ContextualGroup is not redrawn when a new RadTabItem is added dynamically and the ContextualGroup is currently active.
In Windows8 theme, the selected Contextual RibbonTab has an inner border which has to be removed to indicate the selection properly.
When the Ribbon is hosted in a RibbonWindow, the ContextualGroups are rended differently Q3 2013 release.
Add the ability, while holding down a modifier key (for instance ALT which triggers the KeyServices) and pressing the AccessText key at the same time, to execute the action associated with the element. Available in R1 2017 Release Please note that is it working only for KeyDown ActivationModes, not in the default KeyUp.
NullReferenceException design-time exception is thrown in VS designer when the RadRibbonTab is defined as a root element of a UserControl.
Setting Button, TextBlock, TextBox or any other UI Element as a Header of RadRibbonGroup produces a runtime exception: The Element is Already Child of another visual.
When UserControls are dynamically added in the RibbonView Items collection, they are displayed as RibbonTab Headers. Instead they should create a RibbonTab collection where each control represents the content of a RibbonTab. UPDATE: An implicit style can not be applied on derived controls as their TargetType is different than the one defined in the implicit style. Basically if you set the style implicitly, the style is applied only on the types that match the TargetType exactly and not on elements derived from the TargetType value. You can find more information on the topic in the remarks section of the Style property definition: http://msdn.microsoft.com/en-us/library/system.windows.style%28VS.95%29.aspx This is why in order to apply a Telerik predefined style on a UserControl deriving from RadRibbonTab, you need to add a Style targeting the UserControl type in the Resources of the application. It is best to define that style after merging the Telerik ResourseDictionaries so that you can base the UserControl Style on the predefined "RadRibbonTabStyle".
