Improving performance in WPF applications

If you've been using WPF with layered windows to provide transparency [with the Windows.Transparency option set to true], you may have noticed that the performance isn't what you might expect.

A supported hotfix to the problem can now be downloaded. Check out the details here:

I've personally used the hotfix to try out applications that use transparency in WPF and it is terrific!
