Black Flash Only When Opening One Screen

I have several screens in my App Inventor project. Only one screen (5) shows a black flash before it opens. Other screens with more content open smoothly.

I already:

Removed all initialize screen 5 blocks

Set white background

Disabled Scrollable

Delayed screen opening
Still same issue.

Any ideas to fix or reduce the black flash?

Thanks!

How are you opening screen 5, and from where?

From screen 1 WHEN CLICK BUTTON_OPEN ANOTHER SCREEN 5

Do you also open the other screens from Screen1 ?

yes

Is there an image on Screen 5?
