I am re-posting this as it has been closed but not solved.

Here is the XAML for an example window:

<Window x:Class="DropShadowProblem.MainWindow"
        xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:d="https://schemas.microsoft.com/expression/blend/2008"
         xmlns:mc="https://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:local="clr-namespace:DropShadowProblem"
         mc:Ignorable="d"
         Title="MainWindow" Height="340" Width="600" MouseDoubleClick="MainWindow_OnMouseDoubleClick">
     <DockPanel>
         <Canvas Name="Canv">
             <Border>
                 <Viewbox StretchDirection="DownOnly" Width="580" Height="300" >
                     <TextBlock FontSize="400" Foreground="BlueViolet" Text="Hello" >
                         <TextBlock.Effect>
                             <DropShadowEffect ShadowDepth="30"></DropShadowEffect>                         </TextBlock.Effect>
                     </TextBlock>
                 </Viewbox>
             </Border>
         </Canvas>
     </DockPanel>
 </Window> 

And here is the code behind:

using System.IO; using System.Printing;
using System.Windows; 
using System.Windows.Input; 
using System.Windows.Xps.Packaging; 
using Microsoft.Win32; 
namespace DropShadowProblem

{

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

}
private void MainWindow_OnMouseDoubleClick(object sender, MouseButtonEventArgs e)

{

var sfd = new SaveFileDialog { Filter = "XPS files (.xps)|.xps" };

if (sfd. ShowDialog() != true) return;

var c = Canv;

var doc = new XpsDocument(sfd. FileName, FileAccess.Write);

var writer = XpsDocument.CreateXpsDocumentWriter(doc);

writer. Write(c, new PrintTicket { PageMediaSize = new PageMediaSize(c.ActualWidth, c.ActualHeight) });

doc. Close();

}

}

} 

And here is the resulting XPS:

I have detected that for the last 35 days, this issue didn't have any product team activity and a very small amount of new votes or comments. Based on this, its severity, and affected area, it’s my experience that this issue is very unlikely to be fixed.
