Hi, for the records, I notice similar jerky transitions on a fairphone5, with version 1.0.1 The 'bounce' effect when moving from one screen to another is not smooth, IMHO the 'bounce' could be disabled entirely I wouldn't miss it :)

I tried disabling all animations, it improves the experience a lot but sadly in my case it breaks a native feature of the phone (split screen) so it's not really a viable option.

the 'bounce' could be disabled entirely

It happens with folders too, the implementation is inefficient and it must be fixed.

I also noticed the choppiness and the bounce can definitely go.

I think the bounce is an easy fix, just change the OvershootInterpolator to any other interpolator like FastOutSlowInInterpolator. I don't know enough Kotlin nor Android development to fix the performance issues.

Still an issue on 1.1.0 from F-Droid.

Was smooth at first, but very jerky with 3 screens with folders, widgets, etc.

Running GrapheneOS on a Pixel 8 Pro - so not an underpowered device.

Still an issue using 1.1.4 on a Nokia G42 5G. Slow movement between screens. Default launcher and even something ancient like Lawnchair are smooth.

For what it's worth, on my home screen and other pages I organise my apps into lots of folders. Could be an issue where Launcher disregards the folders and thinks there are lots of icons on-screen?

Edit: I'm using the version from F-Droid.
