Animation differs between using .coreAnimation and .mainThread as the rendering engine.

[mingso]

Which Version of Lottie are you using?

Lottie 4.0.1 ~ 4.1.3

Expected Behavior

expected.mp4

Actual Behavior

actual.mp4

Animation JSON

background.json.zip

---

When setting the rendering engine to .mainThread, it operates normally, but an error occurs when setting it to .coreAnimation.

It seems that this issue may be related to this section, as changing the "h" value to 0 in lines 71, 118, and 174, ... of the background.json file results in normal operation.
(However, it may not be related to that section because I don't know what each property means.)

Thank you.

I have the same issue for me as well, I can provide the sample json files, in one mode the knobs are shown, in other not. Also the animationFinished events are different in .mainThread and .coreAnimation modes.
