I just replaced the Microsoft.Windows.Controls.Ribbon with the new System.Windows.Controls.Ribbon.
If I maximize my application the window now seems to be slightly too big. So that the upper left icon and the icons in the QuickAccessToolbar are only shown partially.
Is it enough to just replace the Ribbon, or do I have to do more?
You can reproduce this problem by just creating a new WPF application and using RibbonWindow instead of Window as the base class for MainWindow.
BTW: The MainWindow title disappears when using RibbonWindow.
