Question about scene performance

I am developing a bit of an unusual app with Phaser and I have a question regarding separating scenes and whether they have any effect of performance.

I have a horizontal ticker running across the bottom of the screen in my app (this app is for fireTV) and it scrolls text constantly. It’s simply bitmap text and I have a tween running that moves it’s x position.
The rest of the screen is basically a slideshow of information that is only updating every few seconds.

I have noticed that as my scene makes transitions or loads content every few seconds there is very noticeable ‘stuttering’ in that bitmap text movement. I’m considering moving that ticker to it’s own scene so that it’s updates might not cause the entire screen to be redrawn on the canvas but I’m not at all sure that Phaser works that way.

Can anyone offer any advice in this area? Does a scene with a smaller camera window laid over top of another scene help to divide up render updates on each frame?

Thanks in advance for any advice or knowledge anyone can offer.
