title: Shadow effect and blurry text
body: <p>I would like to add shadows outside tiles in my WPF application, but when I do, the text inside tiles is blurry. I tried this solution: <a href="https://stackoverflow.com/questions/1688384/wpf-dropshadoweffect-causing-blurriness">WPF DropShadowEffect Causing Blurriness</a> , but unfortunately shadow effect seems not to work at all. Are there any special attributtes in Rectangle which should be set? Could you give me some clues?</p>
