On a recent project a client pointed out that a PDF I exported from InDesign was viewed with extreme anomalies on Windows Phone—it looks like the page was broken up into a grid with drop shadows … with some elements still displaying correctly on a top layer. (I would post and image but I’m confident corporate wouldn’t want me to!). It seems as if Windows Phone was unable to display a drop shadow effect. At the moment I don’t have the opportunity to do more testing. Has anyone experience such issues with Windows Phone? I’m trying to get more data on the OS version, etc.
