Hello,
the title bar says it all!

To reproduce:
1. Create a new WPF application.

2. Add references to the NoXaml versions of Telerik.Windows.Controls, Telerik.Windows.Controls.Input, Telerik.Windows.Controls.Navigation, Telerik.Windows.Controls.RibbonView, Telerik.Windows.Controls.Data and Telerik.Windows.Themes.Windows8.

3. Replace MainWindow.xaml with:
<tk:RadRibbonWindow
  x:Class="Test_RadRibbonWindow.MainWindow"
  Title="MainWindow" Height="350" Width="525">
  <Grid>
    <tk:RadRibbonView />
  </Grid>
</tk:RadRibbonWindow>

4. Replace MainWindow.xaml.cs with:
using System;
using Telerik.Windows.Controls;
 
namespace Test_RadRibbonWindow
{
  public partial class MainWindow : RadRibbonWindow
  {
    public MainWindow()
    {
      InitializeComponent();
    }
  }
}

5. Run the application. When full screen a black line appears under the header.

Tested with Windows 8 pro, 64-bits.

Hello Kiril,
I just installed Q3 2013 and the black line is gone.
But it seems that the ribbon view is one pixel to high, as you can see on the top left corner of the attached image.

Hello Dimitrina,
I took the time to see what's happening this week-end.
The problem is that, in my case, the root of the RadRibbonWindow contains a ispecial control to manage the resources of the application. This control descend from ContentControl and not from Panel and it seems that it is not managed correctly from the code/XAML that "merges" the ribbon and the window. Adding a margin of 1 pixel at the top of the container that is inside the control did the trick.
