Hi,

The issue can be easily reproduced by saving and loading the layout on High DPI.

Workaround: save the layout descaling the location of the strips. A sample approach is demonstrated below: 
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();
    }
 
    string layout = @"..\..\layout.xml";
    private void radButton1_Click(object sender, EventArgs e)
    {
        XmlDocument doc = this.SaveLayoutCore();
        doc.Save(layout);
    }
 
    private XmlDocument SaveLayoutCore()
    {
        XmlDocument doc = new XmlDocument();
        XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", null, null);
        doc.AppendChild(dec);
        XmlElement rootNode = doc.CreateElement("RadCommandBarElement");
        rootNode.SetAttribute("Orientation", this.radCommandBar1.CommandBarElement.Orientation.ToString());
        rootNode.SetAttribute("Name", this.Name);
        rootNode.SetAttribute("RTL", this.RightToLeft.ToString());
 
        for (int i = 0; i < this.radCommandBar1.CommandBarElement.Rows.Count; i++)
        {
            CommandBarRowElement lineElement = this.radCommandBar1.CommandBarElement.Rows[i];
            XmlElement lineNode = doc.CreateElement("CommandBarRowElement");
            lineNode.SetAttribute("Orientation", lineElement.Orientation.ToString());
            lineNode.SetAttribute("Name", lineElement.Name);
            lineNode.SetAttribute("LineIndex", i.ToString());
 
            foreach (CommandBarStripElement stripElement in lineElement.Strips)
            {
                XmlElement stripNode = doc.CreateElement("CommandBarStripElement");
                stripNode.SetAttribute("Orientation", stripElement.Orientation.ToString());
                stripNode.SetAttribute("Name", stripElement.Name);
                stripNode.SetAttribute("DesiredLocationX", this.DescaleFloat(stripElement.DesiredLocation.X).ToString());
                stripNode.SetAttribute("DesiredLocationY", this.DescaleFloat(stripElement.DesiredLocation.Y).ToString());
                stripNode.SetAttribute("VisibleInCommandBar", stripElement.VisibleInCommandBar.ToString());
                stripNode.SetAttribute("StretchHorizontally", stripElement.StretchHorizontally.ToString());
                stripNode.SetAttribute("StretchVertically", stripElement.StretchVertically.ToString());
                stripNode.SetAttribute("EnableFloating", stripElement.EnableFloating.ToString());
                stripNode.SetAttribute("EnableDragging", stripElement.EnableDragging.ToString());
 
                int currentIndex = 0;
                for (int j = 0; j < stripElement.Items.Count; j++)
                {
                    RadCommandBarBaseItem itemElement = stripElement.Items[j];
                    XmlElement itemNode = doc.CreateElement("RadCommandBarBaseItem");
                    itemNode.SetAttribute("Orientation", itemElement.Orientation.ToString());
                    itemNode.SetAttribute("Name", itemElement.Name);
                    itemNode.SetAttribute("VisibleInStrip", itemElement.VisibleInStrip.ToString());
                    itemNode.SetAttribute("StretchHorizontally", itemElement.StretchHorizontally.ToString());
                    itemNode.SetAttribute("StretchVertically", itemElement.StretchVertically.ToString());
                    itemNode.SetAttribute("Index", currentIndex.ToString());
                    stripNode.AppendChild(itemNode);
                    ++currentIndex;
                }
 
                for (int j = 0; j < stripElement.OverflowButton.OverflowPanel.Layout.Children.Count; j++)
                {
