[Bug] AOD-lockscreen animation smoothness reduced by Depth Effect Wallpaper

[thekimiz]

Overview

When the "Depth effect wallpaper" (DEW) option is enabled, the animation transitioning from AOD to lock screen loses its smoothness. This is purely a visual defect.

Expected behavior

The display contents follow the gentle animations they were designed with. No irregularities occur.

Actual behavior

The display contents snap into place, not following their original smoothness.

Steps to reproduce

1. Enable DEW in PixelXpert -> Lock screen -> Depth effect wallpaper
   a) Preferred AI model: ML Kit (Pytorch for me stays at "not available on the device (yet)", so I am unable to test with it)
   b) Also on "always on display": OFF
2. Return to the lock screen. The wallpaper adjusts itself by moving around the screen ever so slightly in my case after about a second. This does not always happen, though, or is not noticeable, and most likely is not required to be able to reproduce the issue.
3. Return to AOD.
4. Return to lock screen and observe the content snap which now persists during DEW. It is only present on the AOD to Lock screen transition.

This seems to be happening with any wallpaper. However, the issue is gone when Also on "always on display" is turned ON.

My setup

Pixel 8 (shiba), Android 15 (Pixel Stock AP4A.250205.002), rooted with Magisk 28100, Zygisk LSPosed 1.10.1 (7115), PixelXpert canary-435
