Symptoms
Consider the following scenario:
- You run a Windows Presentation Foundation (WPF)-based application that uses the .NET Framework 3.0 Service Pack 2 (SP2) on a computer that is running a Windows operating system.
- You set the Window.AllowsTransparency property to True. When the True value is set, the application uses layered windows.
- The operating system enters and then resumes from sleep or from hibernation.
- After the system resume, WPF tries to render the contents of the layered windows.
In this scenario, the contents of the layered windows do not appear.
Notes
- The .NET Framework 3.0 SP2 is included in the .NET Framework 3.5 Service Pack 1 (SP1).
- Other issues that this hotfix resolves are described in the following Microsoft Knowledge Base (KB) article:

Cause
