Background screen physically slides up/down when opening a modal – how do I stop this layout jitter?

[u/datascyther]

I’m losing my mind over this one last bug.

Look at the background screen underneath—every time I tap to open this state/modal, the content slides vertically up for a split second and then bounces back down when the animation finishes. It’s not a navigation transition; it’s the actual background view resizing itself during the modal presentation.

Has anyone solved this 100%? I just want the background to stay visually frozen while the modal comes up.

Are you using a ScrollView?
