A little history from this thread: https://forums.macrumors.com/threads/12-pro-stutter-when-closing-apps.2263484/
Then, a flash of PTSD when a couple hours after I installed one of the iOS 16 betas, I experienced the very same issue on my iPhone 13 Pro Max.
I immediately opened detailed feedback (that hasn't been touched since beta).
The issue has been in every iOS 16 and iOS 16.1 release since, even to this day.
A couple things to note about this one:
- At some point in iOS 14, we started seeing this animation stutter when swiping up to go home. It was bad and got worse over time (until a device restart)
- It was so bad in fact that it would often interrupt the action of going home and throw you into the app selection screen
- It was completely hardware agnostic. It didn't matter what model of iPhone you had or even what apps you were using
- This persisted for many months. We have reason to believe it was VERY widespread (100%?) and that some people were a lot more sensitive to the stutter than others. I remember seeing it random b-roll on a MKBHD video and no one batted an eye
- Regular support was unhelpful and often just suggested that people factory reset the device (it only helped for a while)
- I certainly don't mean to take credit, but after months of it, I was losing my mind. I sent one of those angry emails to the tcook address and a member of the executive support team called me the next day
- Over the next couple of days, they had me install a special piece of diagnostic software and also run in a super high diagnostic mode for the next 24 hours. They wanted me to log when I saw the stutter. I stopped logging after the first 50 or so
- A week later, Apple reached out and told me that they found the issue from my logs and are working on an immediate fix
- A couple days later, build 18E5154f was released and this specific stuttering bug was finally squashed

A couple things to note about this one:
- It is also hardware agnostic, though maybe a little less so (how quickly the issue surfaces)
- I saw it on my iPhone 13 Pro Max
- I saw it on my iPhone 14 Pro Max
- I saw it on my iPhone 14 Pro
- It does not seem to be quite as widespread as before
- I do NOT see it on my wife's iPhone 14 Pro Max (yet?)
- I looked for any difference in settings, usage, etc. Was unable to reproduce it
