Symptoms

Consider the following scenario:
  • You run a Microsoft .NET Framework 3.5 Service Pack 1 (SP1)-based Windows Presentation Foundation (WPF) application.  
  • The WPF application uses the hardware rendering pipeline.
  • The application loads and unloads many application domains that contain one or more custom WPF add-in components.
In this scenario, the application encounters a System.Runtime.InteropServices.COMException exception, and then the application crashes.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Workaround

To work around this issue, disable the hardware rendering pipeline, and then enable the software rendering pipeline.

To disable the hardware rendering pipeline, and to enable the software rendering pipeline, use one of the following methods:
  • Set the System.Windows.Interop.RenderMode enumeration.

    The following is some example code that sets the System.Windows.Interop.RenderMode enumeration to enable the software rendering pipeline when a WPF window is loaded:
    private void OnLoaded(object sender, EventArgs e)
    {
    System.Windows.Interop.HwndSource hwndSource = PresentationSource.FromVisual(this) as System.Windows.Interop.HwndSource;
    System.Windows.Interop.HwndTarget hwndTarget = hwndSource.CompositionTarget;

    hwndTarget.RenderMode = System.Windows.Interop.RenderMode.SoftwareOnly;
    }
  • Set the DisableHWAcceleration registry key.

    Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
    322756  (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows


    Warning This method disables hardware rendering pipeline for all WPF applications on the computer. Therefore, the method is not encouraged usually except when the customers control the environments and do not mind the effect for all WPF applications.

    1. Click Start, click Run, type regedit, and then press ENTER.
    2. Locate and then click the following registry subkey:
      HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics
    3. Set the value of the DisableHWAcceleration registry entry to 1.

      Note If the DisableHWAcceleration registry entry does not exist, right-click the registry subkey, point to New, and then click String Value to create a new registry entry. Type DisableHWAcceleration for the name of the new registry entry, double-click DisableHWAcceleration, and then change the DisableHWAcceleration value data to 1.
    4. Exit Registry Editor.
