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.
