Consider the following scenario:

• On a computer that runs Windows Vista or Windows Server 2008, you enable Aero desktop theme effects.
• This enables the Desktop Window Manager (DWM) feature.
• After you do this, the content for some applications do not fully display the necessary images.

For example, when you visit a Web site by using Internet Explorer 8 Beta, the content in the Web site is not fully displayed. If you refresh the Web page when this problem occurs, this problem is resolved temporarily.

Note: This problem usually occurs on a computer that has a multi-core processor and a large monitor.
