App crashes on Samsung Galaxy S6 (Android 7.0+) with `opacity: 0.99`

Bug description: Our app has a WebView wrapped in View, on which we set opacity: 0.99. On the Galaxy S6 (and a few other similar models, such as S6+, S6 Edge, etc…) with Android 7 or 8, the app will crash once the WebView renders.

If the OS is downgraded to Android 6, it stops crashing. If I change to opacity: 1, it also stops crashing. We’ve not seen crashes on any other devices.

To Reproduce: This is the commit which introduced the crash to our app: https://github.com/jd20/react-native-signature-pad/commit/46ae4459514e14ef4bdc1f1872bc727dad8b4c77

Generally though, the WebView code looks like:

    <View style={containerStyle} onLayout={onLayout}>
      {size && (
        <View style={size}>
          <WebView
            ref={setRef}
            automaticallyAdjustContentInsets={false}
            onMessage={onMessage}
            onLoadEnd={start}
            renderError={onError}
            renderLoading={loader}
            source={source}
            javaScriptEnabled={true}
            style={{
              ...StyleSheet.absoluteFillObject,
              backgroundColor,
              opacity: started ? 1 : 0,
            }}
          />
        </View>
      )}
    </View>

Expected behavior: Not to crash.

Environment:

• OS: Android
• OS version: 7.0
• react-native version: Any react-native version
• react-native-webview version: 11.3.1

Removing the opacity: 0.99 seems to work fine. I’ve not seen crashes on any other devices so far, after removing it.

While that’s a valid workaround, would be great to fix underlying issue, so if someone really did need to set opacity: 0.99, it wouldn’t crash the app.

Do you mean that setting opacity fix some crashes but sometimes cause crash? Or just can’t fix?
