Description
### Current behaviour
ActivityIndicator is visually bugged on android 8.0 (tested on J5 Prime phisical device and on android Simulator)
This bug happens on Buttons with `loading` prop too.
This error start happening after upgrading to RN 0.72. On RN 0.71 this does not happens.
### Expected behaviour
It should not be buggy
### How to reproduce?
Just add an empty view with an ActivityIndicator or a loading button:
```
import { View } from 'react-native'
import {
ActivityIndicator,
configureFonts,
MD2LightTheme as DefaultLightTheme,
Provider as PaperProvider,
MD2Theme,
Button
} from 'react-native-paper'
import { Fonts } from 'react-native-paper/lib/typescript/types'
function Index() {
const defaultFonts: Fonts = {
regular: {
fontFamily: 'Poppins_400Regular',
fontWeight: "400"
},
medium: {
fontFamily: 'Poppins_500Medium',
fontWeight: "500"
},
light: {
fontFamily: 'Poppins_300Light',
fontWeight: "300"
},
thin: {
fontFamily: 'Poppins_100Thin',
fontWeight: "100"
}
}
const fontConfig = {
ios: defaultFonts,
android: defaultFonts
}
const currentTheme: MD2Theme = {
...DefaultLightTheme,
mode: 'exact',
dark: false,
fonts: configureFonts( {
isV3: false,
config: fontConfig
} ),
roundness: 8,
colors: {
...DefaultLightTheme.colors
}
}
return
Test 1
Test 2
}
```

Contributor guide
Research direction
Start by reproducing the minimal ActivityIndicator and loading Button example on Android 8.0 with React Native 0.72.6, then compare the rendering with React Native 0.71. Investigate the Android-specific rendering path implicated by that version change; the issue is done when both controls render correctly on the reported device and simulator.
