UICollectionView vision becomes small for a few seconds when cell tap

UICollectionView vision becomes small for a few seconds when cell tap See image [Before]

[After]

In practice, when I press on the cell (tap) it should tag the element, on iOS 17 it works perfectly, on iOS 15.8.1 however it has the ugly effect of shrinking the entire content of the collectionview for a few seconds.

Can anybody help me ? I don't know where to look anymore
