[ios] Inverse scale transforms results in pixelated blurred poor resolution views

Description

We have a production app where we have a pinch gesture handler that allows pinch zooming on a map. When the map is zoomed in (scaled up) the child POIs are scaled down to preserve sizing of POIs. Example, if the parent View is scaled by 100 the child POI View is then scaled by 0.01 to counteract the transform and preserve sizing. This works perfectly on Android; however, IOS results in a very pixelated render of the child POI View. It appears on IOS, when a View has nested scale transforms applied such that they are inverse the resulting render is pixelated. On Android the View appears high resolution as expected. (See screenshots below).

See main code in app/{tabs}/index.jsx of repro.

Steps to reproduce

Both Architectures: Paper & Fabric

IOS

1. Install dependencies npm install and npx pod-install
2. Run npx react-native run-ios or npm start and open on ios expo
3. Notice blurred blue View when it should be a solid red square with blue border (bug)

ANDROID

1. Install dependencies npm install
2. Run npx react-native run-android
3. Notice solid red square with blue border (expected)

React Native Version

Actual (IOS):

Expected (Android):

Bắt đầu với app/{tabs}/index.jsx của reproducer và thực hiện các bước iOS được liệt kê bằng React Native 0.76.6 trong cả Paper và Fabric. So sánh kết quả trên iOS với Android, tập trung vào các phép biến đổi scale nghịch đảo lồng nhau. Hoàn tất khi child view trên iOS được render thành một hình vuông màu đỏ đặc với viền xanh dương thay vì một view bị mờ và vỡ pixel.
