Patrick,

I have no answers. All I can do is provide some solidarity. I'm trying to animate an ItemsControl. The concept is pretty simple, really. I've got a ListView and in the ListView I have a GridView. I want the items in the GridView to to smoothly go from one row to another row as the underlying list is sorted so that, for example, a sorted list will stay sorted as the values in the list change.

I've noticed this: animation on moderately complex controls is a CPU hog. The stuttering I'm pretty sure is simply related to the CPU being maxed out (I noticed you didn't provide the CPU graph on your dump above). Keep the CPU around 50% and the animation appears smooth, above 75% and you get these stutters. Still working on the problem, but I think it goes deeper than my code.
