Problem with rotating multiple sprites on one GO

I’m trying to create card game and I am making card from multiple pieces. There is a big back part and 4 small parts in the front (in a grid like position). They have different z position, so they don’t overlap. Then I’m trying to rotate this object around Y axis and card start flickering.

I made a small project with two cards. Front part of the left card is made from 4 sprites. Front part of the right card is just one sprite. They equally rotates with go.animate, but the result on screen is different.

I expected they both should look the same. Then I think maybe it because of sorting and stuff, but defold renders everything with depth buffer, and it should fix the result order of pixel? Maybe i need to put something in render script?

Whole project.
