I came across this problem, although my theory was that the window was being sized from small to larger, which of course makes springs and struts whacko when views ares forced to overlap. Even auto layout doesn't solve it quite--I had to make sure that every subview had a fixed position. Even then, the content view would have a bad origin (0,-8) and I had to override setFrame: to correct it. This might have been a 10.7 bug, as I haven't tested it since. There may be a way with auto layout-based animations, but I haven't the wherewithal to pursue it.
