Issue 1When you change the value of the VisualBrush.Visual property in a WPF application, the application crashes.
Issue 2A memory leak occurs in the render thread of a WPF application when you perform one of the following actions:
- You use the software-rendering pipeline to render a 3D scene that includes a VisualBrush object or a DrawingBrush object. For example, you are using the software-rendering pipeline when you perform one of the following actions:
- You render the scene by using the RenderTargetBitmap class.
- You print the scene.
- You set the rendering tier property to 0.
- You render the scene over a remote desktop connection.
- You render a scene by using the WriteableBitmap class on a computer that does not use the Windows Display Driver Model (WDDM).
- You use the hardware-rendering pipeline to render a scene by using a tiled VisualBrush object or a tiled DrawingBrush object on a computer that does not use the WDDM.
Issue 3WPF applications that use layered windows crash when you perform one of the following actions:
- You put a computer that uses the Windows XP Display Driver Model (XPDDM) into standby, and then you resume the computer from standby.
- You switch to the full-screen console mode on Windows XP.
Cause 1This issue occurs because a generic error is returned from a render thread when the operations in the thread are ordered incorrectly. These operations cause child objects to detach from a null parent object.
For example, a Visual object must be removed from a VisualBrush object before it is detached from the VisualBrush object. However, the operations to remove the Visual object may be ordered incorrectly. Therefore, the Visual object detaches from a null parent object.
Cause 2This issue occurs because of a reference counting error in the render thread.
Cause 3This issue occurs because a Win32 error code is handled incorrectly.
