Hello,

As a workaround I can suggest you two possible options:
1. Programmatically resize the form to update the layout of RadRibbonBarBackstageView.
2. Use reflection to call the method that updates the bounds of RadRibbonBarBackstageView.
private FormWindowState lastWindowState;
  
public Form1()
{
    InitializeComponent();
    this.lastWindowState = this.WindowState;
}
          
protected override void OnSizeChanged(EventArgs e)
{
    base.OnSizeChanged(e);
  
    if (this.lastWindowState == FormWindowState.Maximized)
    {
        this.lastWindowState = this.WindowState;
  
        // Option 1. Programmatically resize the form
        this.Width += 1;
        this.Width -= 1;
  
        // Option 2. Use reflection to call the method that updates the RadRibbonBarBackstageView bounds
        // MethodInfo sizeChangedMethod = this.radRibbonBarBackstageView1.GetType().GetMethod("parentControl_SizeChanged", BindingFlags.NonPublic | BindingFlags.Instance);
        // sizeChangedMethod.Invoke(this.radRibbonBarBackstageView1, new object[] { this, EventArgs.Empty });
    }
  
    this.lastWindowState = this.WindowState;
}
