Exe logo in task manager is strected for win-ui 3 application.

Question

Hi, I am currently working in an Win-Ui 3 Project, where i have added the icon to my application, but the thing is while running the application in task manager, the application icon is stretched out and not displaying properly in windows 11 . In Windows 10 icons are coming properly in task manger.

Steps to reproduce the bug

1.Create a winui-3 project.
2.In mainui.csproj add "Assets\Test.ico".
3.In mainwindow.xaml.cs class "AppWindow _appWindow;" , & In constructor "_appWindow.SetIcon(@"Assets\Test.ico");".
4.Run The application.
5.Open Task Manger and expand the application.

Expected behavior

Logo should display without strecthing in task manager.

NuGet package version

WinUI 3 - Windows App SDK 1.2.3: 1.2.230118.102

Windows version

Windows 11 (21H2): Build 22000

Additional context

Note: This issue us mainly coming in windows 11 OS, I've added the screen shot of windows 11 and windows 10

Did you test with WM_SETICON and various formats as I posted on your issue on GitHub ?
