Driving Car Scene

So I am writing a story and I’m trying to transition into my cart scene with transition fade in black 3. So when I do that it glitches a little bit and then everything looks normal, I hope this makes sense and I’m not sure how to fix it. It looks fine on desktop but when I view it on phone it glitches then goes to normal. How do I fix this?

If it is only glitching on your phone then it is probably just your phone, if you want you can send me the link to your story to see if it happens to me?

Maybe try writing the overlay next to the background, for example:

INT. BACKGROUND - DAY with OVERLAY_NAME to % x y in zone # at layer #
