I got basic cub with 4 sprites on over it with different Z coordinate.

When im rotating this object sprites are flickering and sometime drawing behind cube. From some angles they are drawing right. I tryed to set offest in shader, change near and far cliping planes - no result. This happens in game mode and in editor mode. Same in empty scene with default camera.

I was using unlit/transparent shader.

To solve this you need to use unlit/texture and quads rather then sprite.
