Motion trails since 4.3.0

[AlasdairWem]

Hi all 👋

We've noticed lagging/trails/tracing on the dots in this animation when they move together after full pin entry.
The animation is two separate Lotties cycling from one to the other.
The problem *becomes noticeable here: ecdadec
Our configuration of the view is unaltered.

Which Version of Lottie are you using?

4.3.2

Expected Behavior

Simulator.Screen.Recording.-.iPhone.14.Pro.-.2023-09-27.at.12.02.13.mp4

Actual Behavior

Can you please share a sample project that demonstrates this issue? When I test the stageThreeBottomTopTop animation locally I don't see any unexpected trails or artifacts.

Hey, thanks for the quick reply. One extra bit of info, we're actually cycling between two animations here, this is the other one. I wonder if jumping from one to the other is causing the problem.
I'll get a demo project setup asap 👍

On closer inspection, my suspicion is that the animation/layer isn't removed as quickly as it was previously on completion, hence showing a trace of the old when the new begins. Perhaps there's something we can do to work around this?

Able to reproduce in the project attached -
