The selected tab content ScrollBar appears when there are RibbonGroups which size can be changed to smaller size.

RotateTransform is not applied correctly on elements defined in the Content of the window.

Reason for declining: The issue appears to be in the framework as it is not calculating correctly the transformation and instead of rendering the transformation it apply a Clipping to the parent element. You could solve the issue by two different approaches: you could either set the UseLayoutRounding of the Window to false, or set the Width/Height properties of you element to be Integer numbers, not double (10.782). You can reproduce the same behavior with the MS Window simply set its UseLayoutRounding to true. You can find attached project reproducing the issue only with MS controls.

A binding error occur in the output on Windows7 without aero.

PLEASE can you remove the popups that appear in the Blend and Visual Studio designers when working on the RadRibbonView.  These popups popup all the time, they cover the code, they cover the design workspace, in VS the switch from the code window to the designer window as soon as you click on portions of the code with no warning, then you can't get back to the code screen until you click away from the RibbonView.  Its 'so' annoying - I've been editing in Notepad++ today because the RibbonView designer functionality makes Blend./VS is unusable.  Also, the popups don't provide anything that you can't do in either code or the Blend interface.  Wasted so much time today with this RibbonView.

Declined: The RadRibbonView control exposes a design time logic to make our clients that uses only the designer to populate and operate with the RadRibbonView control. If you want to disable that functionality you need to simply delete the following binaries from you design folder, which is located in the same directory as the Telerik binaries:
- Telerik.Windows.Controls.RibbonView.VisualStudio.Design
- Telerik.Windows.Controls.RibbonView.VisualStudio.Design.4.0
- Telerik.Windows.Controls.RibbonView.Expression.Design
- Telerik.Windows.Controls.RibbonView.Design.5.0
- Telerik.Windows.Controls.RibbonView.Design.4.0
Doing so you will remove the design time functionality of the RadRibbonView in all VisualStudios/Blend.

Opening the Backstage on RibbonView's Loaded event workarounds the issue.

Office 2016 has a search field in the ribbon for quick access to commands that may be hard to find.
Can such functionality be added to the telerik ribbon ?

Declined: We consider this functionality to be an Application logic as the information that need to be displayed is based on the UI(the defined options/buttons in the RibbonView). Also the keywords for activating a given option may be different based on client preferences or language. This functionality can easily be achieved with a custom Style for the RadRibbonTab, containing only the control which you will use for the search (RadAutoCompleteTextBlock/RadWatermarkTextBox e.t.).

Workaround:
In the Loaded event of the RibbonWindow, use the Telerik.Windows.Controls.RibbonView.Shell.WindowChrome class to get the current window and set its ResizeBorderThickness property to 0. 

public MainWindow()
{
    InitializeComponent();
    this.Loaded += MainWindow_Loaded;
}
 
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    Telerik.Windows.Controls.RibbonView.Shell.WindowChrome chome = Telerik.Windows.Controls.RibbonView.Shell.WindowChrome.GetWindowChrome(this);
    chome.ResizeBorderThickness = new Thickness(0);
}
