On a Windows Vista-based computer that includes PowerXpress technology, you enable the Windows Aero feature. When you switch from integrated graphics to discrete graphics, the Direct3D (D3D) application stops rendering graphics.

The problem also occurs in the following scenario:

• You have a Windows Vista-based computer that has more than one graphics processing unit (GPU).
• You switch from one GPU to the other GPU.
• You use Device Manager to manually disable the GPU from which you switched.
