Description
Description
It seems Android has trouble displaying the correct border colors when borderRadius exceeds a certain value.
The use case here is having an easily reusable style or component which can be circular regardless of the size; most easily achieved by setting a high border radius. Given that this works as intended on iOS and web, I assume it is a supported use case. If border radius is not intended to exceed a certain calculable value it should be noted in the docs somewhere but I was unable to find any relevant information. Alternatively, It might make sense to clamp the value in the RN core code but I'll leave that to the maintainers to decide.
Based on my testing this issue only impacts Android as you can see in the screenshots from the snack I've linked below.

I've seen some other recent issues around border radius on Android but none of them seem to be directly related to this particular behavior based on my understanding so apologies if this is a duplicate, obviously feel free to close/merge in that case.

Steps to reproduce
- Create a
<View />. - Give the view different colors for each of
borderTopColor,borderBottomColor,borderRightColor, andborderLeftColor - Set the view's
heightandwidthto any number,n - Set the view's
borderRadiusto any number greater thann/2 - Observe the coloration of the border. Optionally, you can change the
borderRadiusvalue to see how the colors change with different values.

Piste de recherche
Commencez par exécuter le Snack lié et reproduire le comportement d’Android avec différentes couleurs de bordure et un borderRadius supérieur à la moitié de la taille de la vue. Suivez le point d’entrée du border-rendering de React Native sur Android, puis vérifiez le résultat par rapport aux captures d’écran iOS et web ; c’est terminé lorsque les couleurs de bordure Android restent correctes pour le cas de rayon signalé.
