RibbonView: High CPU usage at design-time in the themes from Office2016 and newer
This is tested and reproducible in the Office2016 and Material themes. Probably it can be reproduced also with other new themes which use glyphs.

The CPU goes high because the RadRibbonGroup contains a GroupChrome element which has a TextBlock with the GlyphAdorner.ShowGlyphInDesignTime property set to True. 

To resolve this:

1.Extract the ControlTemplate of the RadRibbonGroup control.
2.Extract the ControlTemplate of the GroupChrome control.
3.Find the TextBlock element in the GroupChrome ControlTemplate.
4.Remove the telerik:GlyphAdorner.ShowGlyphInDesignTime  setting from the TextBlock
5.Set the Template of the GroupChrome in the RadRibbonGroup ControlTemplate to the custom GroupChrome template.
6.Apply the custom RadRibbonGroup template.
