If I add a RadLabel to a RadPanel, and set the panel AutoScroll to true, scrolling the panel will cause lines to appear.  The words get clipped.

1. Create RadRibbonForm and add code to start maximized 
2. Add status strip with some items on the ribbon form 
3. in the form constructor create a MDI child form, set it to start maximized and show it 
4. The result is that there is gap between the child form and the status strip

Workaround:
protected override void OnShown(EventArgs e)
{
    base.OnShown(e);
 
    this.WindowState = FormWindowState.Minimized;
    this.WindowState = FormWindowState.Maximized;
}

When RadPanel is set to AutoSize, it should update its size automatically when changing the visibility of some control inside it.

Workaround:
 public class CustomRadPanel : RadPanel
    {
        public override string ThemeClassName
        {
            get
            {
                return typeof(RadPanel).FullName;
            }
            set
            {
                base.ThemeClassName = value;
            }
        }

        protected override void OnLayout(LayoutEventArgs e)
        {
            base.OnLayout(e);
            int maxHeight = 0;
            foreach (Control control in this.Controls)
            {
                if (control.Visible)
                {
                    maxHeight = Math.Max(control.Height, maxHeight);
                }
            }
            this.AutoSize = false;
            this.Height = maxHeight;
        }
    }

Create a custom theme starting from Aqua theme. Change the Font for RadLabelElement-TextPrimitive to "Microsoft Sans Serif, 10pt". Save the theme and apply it to the entire application. Show several times a RadMessageBox with long text. The first time the RadMessageBox is sized correcly to its content. Each next showing, cuts off the text.

Workaround:  the possible workaround that I can suggest is to dispose the RadMessageBox instance after showing it:

Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
    RadMessageBox.Show(Me, "If you have some veeeeery long sample text, the messagebox " & _
                       "should be resized according to its content.", "Caption", MessageBoxButtons.OK, My.Resources.image)
    RadMessageBox.Instance.Dispose()
End Sub
