Visual bugs when changing many item's heights

[psi-gh]

When updating heights of multiple items (18 items in my example), I've got a visual bug - flickering effect with new (updated) items are flowing up from the bottom of collection and moving to some top position beyond the screen. I attached video when you can see it if you will look frame-by-frame. I also attached a screenshot of the middle state of this animation.
