SceneKit overlaySKScene with wrong Textures for some frames (iOS, Swift)

For my SceneKit App I use overlaySKScene as a SpriteKit HUD. The Sprites (PNGs) are preloaded and comes from an atlas. Some of them are animated an some not. Now comes the strange behaviour: Sometimes it shows wrong textures of the Sprites for 1 or 2 frames.

For example: I have two sprites on that overlay, sprite A und sprite B. It presents sprite A at the beginning correct and then for just one or two frames it shows the texture of sprite B.
I think its a bug of the SceneKit or SpriteKit framework during the rendering of the frames.

Does anyone have a solution for this?
