It also depends on the speed with which you pinch 4-5 fingers, try the gesture a little slower, keeping your fingers on the glass, and the animation won't stutter and offend your delicate sensibilities.
As a bonus, you can reverse the gesture before the operation is fully completed if you change your mind, and watch the home screen icons swoop in and out in slow motion as you pinch it's like watching an expertly choreographed app-launcher ballet!
Still, I feel as many others do around these forums, the stuttering animation glitch in 7.0 is just about the worst thing in the world and every time it pops-up I want to slit my ****ing wrists.
Nah, not with this gesture but a few of the new ones aren't as smooth as they could be. Nothing big and I expect an OS release will take care of some of the trivial movement issues.
