📜 Description
TBD
💡 Motivation and Context
TBD
One screen of the dogfooding app Flinky had the following masking issue in a screen where a Grid and a List are inside a VStack, where the entire top half was unmasked:
Further analysis using
(lldb) po view.value(forKey: "recursiveDescription")!surfaced that theSwiftUI.Listis implemented as aSwiftUI.UpdateCoalescingCollectionView, a subclass ofUICollectionView, which uses a_UICollectionViewListLayoutSectionBackgroundColorDecorationViewto display its background color.This background view massively overextends the list bounds with it's frame of
(-20 -1135.33; 442 2336)and causes calculation issues in the clipping.The easiest solution for now was simply ignoring the view from the redaction algorithm.
💚 How did you test it?
I used the Flinky project with a locally checked out Sentry Cocoa SDK repo and directly compiled it. After running the app I checked the replay in Sentry.
