Exactly the same problem for me! Everything was ok for weeks and since yesterday the stuttering is back. Unbelievable.
A reboot gives me about 12-24 hours (sometimes more, sometimes less) without stutters. So if you reboot frequently it may seem like they are gone for a while.

Interestingly enough, I saw the lag when swiping back to home screen for the first time on my 11" M1 iPad Pro (iPadOS 16.2).

I don’t know about the swipe home stutter so far but I can tell you on 16.3 beta 2 games like genshin still stutters on my iPhone 14 pro max.

Yeah, it seems to be way more widespread than initially thought. I saw it for the first time on my wife's iPhone 14 (non Pro) this past weekend. I also saw it on my dad's iPhone 12 (non Pro) while helping him with something.

This has been an issue in virtually all devices for 2 years….apple isn’t gonna fix it. Sometimes it’s smooth as butter. Other times there’s a weird lag/delay. This broke in iOS 14. When iPhone X, XR, XS were new everything was SMOOOTH. In fact XR was the smoothest device on iOS 12 I ever used
yeah, you are right

For what it's worth, I haven't seen the stuttering since I upgraded to 16.2 on my 14 Pro

Have you closed your recent apps or been rebooting the phone?
I close recent apps when I remember to (a couple of times a week), and reboot my phone once a week. Same behavior I’ve done since forever and definitely no changes on my end compared to iOS 16.0-16.1

16.2 definitely fixed the stutter for me.

Sporting a 14 Pro Max since 2 weeks, after one year on an iPhone 13 Pro: never seen something similar to stuttering or frame drops.
Actually every year we have this kind of threads (or kind of) from some users.

I remember seeing that this issue happened once before when iOS 13 or 14 came out, and that it was eventually fixed. How long did it take to fix back then?

It's really strange. I had this problem hourly on my phone since I got it until the day 16.2 got released.
Still no stutters to this day. Not a single one. Had them every single time I picked up my phone before.

Didn't uninstall any apps, didn't change my settings - nothing. It's just gone. Haven't done a single restart since the update, and I do not close 'running' apps.

It's great that it's actually fixed for you. My support ticket with Apple shows as "Potential fix identified for iOS 16.2". So maybe this is caused by several different things and they happened to address the one that was causing it for you.

It took until the end of April last time with iOS 14 on iPhone 12.

I’m on 16.3 beta 2 and this bug is still very much present. It took a few days to show itself but now it is constant unless I reboot my phone.

what’s happening is an issue with pro motion displays and the variable refresh rate of the display not ramping down consistently enough when pushing an app out of high refresh 120hz into the home screens more static 1-10hz area. the animation stutters before dumping the app into ram. a firmware update would correct how the display enters a lower power refresh state from a higher 120hz active use app state.

this issue does not happen with iphone 14 (non pro) or any device without a pro motion or high/variable refresh rate display technology.

Only if apple could understand this similar to how you did. This reason makes a lot of sense!

Unfortunately this issue also happens in my regular iPhone 13 without a pro motion display, so that might be only one of the problems. @MagicMiguel also mentioned that he saw it on a regular iPhone 12 and iPhone 14.
