Is there any way to improve the display of a WPF application which renders everything using AntiAliasing. As I understand it WPF pipes this through DirectX, any attempt on my part of altering the OS settings for ClearType etc...has had no effect. Running Parallels4 with new install of XP SP3, .NET 3.5 SP1, any WPF application has a graining effect over top of text and graphics and commonly also I see blackened backgrounds on text and images also. The following Family tree software is a good example, it's only a 2Mb install http://www.vertigo.com/familyshow.aspx
