Rendering issues after the September 12, 2017, .NET Security and Quality Rollups are installed

Applies to: .NET Framework 4.6.NET Framework 4.6.1.NET Framework 4.6.2

Symptoms


After you install the September 12, 2017, .NET Security and Quality Rollups that apply to the .NET Framework 4.6, 4.6.1, 4.6.2, and 4.7, you experience rendering issues in Windows Presentation Foundation (WPF) applications that use WPF types in a Windows service.

When these issues occur, applications that use a WPF element for rendering generate a black image. This occurs if the application is running in the following situations:

  • In a non-interactive Window Station (for example, within Windows Services)
  • Running as a LocalSystem account
  • Interactively in Session 0 by using tools such as psexec.exe
