WPF application is crashed when Discord captures its screen

Dev-Taehui commented 1 year ago

Description

All wpf apps is crashed when user starts capturing its screen with using "Use our advanced technology to capture your screen" option of Discord. It is regardless of .NET framework, .NET Core 3.x or .NET. I think that it is relative to WPF DirectX 9 hardware acceleration. Because when I turned off HW acceleration, it doesn't crash anymore.

Reproduction Steps

Create any wpf project.
Build and start.
Execute Discord and start screen sharing of wpf app.

Expected behavior

Not crashed

Actual behavior

Crashed

Regression?

No, Visual Studio 2022 that is based on .NET framework is crashed when Discord hooks it to capture screen

Known Workarounds

No
