TouchableOpacity on Android with elevation and rgba background causes clipping/octagons

[zibs]

Description

Android's TouchableOpacity has weird clipping/octagons when it's used with elevation and an alpha channel background color i.e rgba(hex, hex, hex, 0.5). This is reproducible both in an expo snack, and with a new react-native init using 0.65 etc.

It seems like this issue is partially covered by #26544 - but it's been open for a few years and has diverged perhaps from the original issue. I've posted a follow up comment there: #26544 (comment)

iOS is fine:

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Create blank project (either Expo snack/new 0.65 npx react-native init)
2. Create a TouchableOpacity component and give it some elevation and an rgba background color
3. Witness clipping/octagons

Expected Results

I'd hope that we could have the same behaviour iOS has?

[lufercampos]

same here, only Android.
I am trying to use elevation in a view inside the TouchableOpacity:
${st.ifProp( 'shadow',elevation: 2;
shadow-color: #000000;
shadow-offset: 0px 4px;
shadow-opacity: 0.16;
shadow-radius: 8px;, null )}

This issue only occurs on Android

Yes, can reproduce this issue. Using shadow, elevation and associated shadow styles in a view inside TouchableOpacity results in clipping/cutouts/borders/whatever you can name.

The solution is to remove shadow and associated shadow styles from the view and add these styles to the main TouchableOpacity container.

*For reference only

Before:

 <TouchableOpacity style={{ flex: 1 }}>
  <View 
    style={{ 
      shadowColor: "grey",
      shadowOffset: { width: 0, height: 4 },
      shadowOpacity: 0.1,
      elevation: 4,
      borderWidth: 1,
      borderRadius: 30
      width: 60, 
      height: 60 
    }}
  >
  <Text>Some text</Text>
  </View>
  <Ionicons 
    name="circle" 
    size={30} 
    style={{  
      position: "absolute",
      alignSelf: 'center',
      paddingTop: 20,
    }}
  />
</TouchableOpacity>

After:

 <TouchableOpacity 
   style={{ 
     flex: 1,
     shadowColor: "grey",
     shadowOffset: { width: 0, height: 4 },
     shadowOpacity: 0.1,
     elevation: 4,
   }}
>
  <View 
    style={{ 
      borderWidth: 1,
      borderRadius: 30
      width: 60, 
      height: 60 
    }}
  >
  <Text>Some text</Text>
  </View>
  <Ionicons 
    name="circle" 
    size={30} 
    style={{  
      position: "absolute",
      alignSelf: 'center',
      paddingTop: 20,
    }}
  />
</TouchableOpacity>
