PipelineVisualFactory BlurEffect crash when run on VM

Open kjean667 opened this issue 1 year ago • 6 comments

Describe the bug

Using PipelineVisualFactory effects in XAML, such as BlurEffect or GrayscaleEffect from the CommunityToolkit.WinUI.UI.Media library, throws an unhandled exception when application is run on a virtual machine (Hyper-V).

This may cause the application to crash.

Regression

Unknown

Reproducible in sample app?

  • [ ] This bug can be reproduced in the sample app.

Steps to reproduce

  • In Visual Studio, create a new project using the template "Blank App, Packaged (WinUI 3 in Desktop)".

  • Add the nuget package CommunityToolkit.WinUI.UI.Media to the project.

  • Use the following XAML in MainWindow.xaml:

  xmlns:media="using:CommunityToolkit.WinUI.UI.Media"

  <StackPanel>
    <TextBlock Text="Testing" Margin="10"/>
    <media:UIElementExtensions.VisualFactory>
      <media:PipelineVisualFactory Source="{media:BackdropSource}">
        <media:BlurEffect Amount="2" />
      </media:PipelineVisualFactory>
    </media:UIElementExtensions.VisualFactory>
  </StackPanel>
  • For stack trace of the problem, add the following to the App.xaml.cs and include nuget package System.Diagnostics.EventLog:
    public App()
    {
      UnhandledException += OnUnhandledException;

      this.InitializeComponent();
    }

    private void OnUnhandledException(object sender, Microsoft.UI.Xaml.UnhandledExceptionEventArgs e)
    {
      EventLog eventLog = new();
      eventLog.Source = "Application Error";
      eventLog.WriteEntry(Package.Current.DisplayName + ": Unhandled exception.\n" + e.Exception, EventLogEntryType.Error);
    }
  • Package the application into an msix and install the package in a Windows installation running in a Hyper-V VM.

  • Start the application.

  • Check the EventLog in Windows, where the exception will be logged under the Program category.

Expected behavior

Either:

  1. The effect shall be made to work even when run on a Hyper-V VM or
  2. The exception shall be handled and the effect creation shall be skipped because the hardware does not support it.

The application shall not crash.
