SVG components disappearing on navigating back for Android

[fedpre]

Description

I have written a custom SVG component to apply an overlay fading

          <Svg
            pointerEvents="none"
            height="100%"
            width="100%"
            style={[StyleSheet.absoluteFillObject, styles.svg]}>
            <Defs>
              <LinearGradient id="grad" x1="0%" y1="0%" x2="0%" y2="100%">
                <Stop offset="0" stopOpacity={0} />
                <Stop offset="0.4" stopOpacity={0.3} />
                <Stop
                  offset="0.8"
                  stopColor="rgb(50, 50, 50)"
                  stopOpacity={0.7}
                />
                <Stop
                  offset="1"
                  stopColor="rgb(10, 10, 10)"
                  stopOpacity={0.8}
                />
              </LinearGradient>
            </Defs>
            <Rect width="100%" height="100%" fill="url(#grad)" />
          </Svg>
          
 const styles = StyleSheet.create({
  svg: {
    zIndex: 99,
    pointerEvents: 'none',
  },
});

I am on the latest react-native-svg version to date (15.4.0) and I am still experiencing the issue reported in this older issue here where a glitch happened just before navigating back. I checked the code that resulted in a fix in that issue and it's mostly present in the library, although there have been a regression change a whilte ago (you can check the history in the issue).

Am I missing something? As you can see from the video, the SVG is clearly disappearing and it is happening to each SVG fading overlay that I use in the app. If you slow down the video, you can easily see that.

Is it possible that something got broken while making the change? Am I doing something wrong? Any possible solutions? Thanks!

Hi @fedpre, is there something that indicates that the issue is caused by react-native-screens? Have you tried disabling screens (uninstalling it & using regular JS based stack)?

Hi @kkafar, yes, if I use the normal JS stack I do not get the odd behaviour, which means that it works correctly. That's why I believe it is a react-native-screens issue?

Hey maybe it could be related to this #2065 since the svg view also has absolute position

Could you check if the element disappears or just the zIndex doesn't work? (for example by making underling views semi-transparent). What I observed in #2065 is that views aren't sorted properly by zIndex when animating exit, but they are there.

Btw. @fedpre could you provide a minimal repo in a snack? Current snack does not work. And If it's the problem with #2065 moving overlay as the last element should work as a fix.
