Looks like an acrobat bug to me; if you use gsview, it works ok; there are more problems with acrobat and transparencies, like - no smoothing when a vector graphic is on top of a transparency - disappearing characters (esp very big ones) - funny flattener preview colors One of the reasons for such problems is that there is no 'reset graphics state' operator and i guess that occasionally the acrobat graphic state stack gets messed up.
