[Android] semi-transparent png textures are rendered black on first load #663

Submission checklist

• I have confirmed the issue is present in the latest version of the rive Flutter package
• I have searched the documentation and forums and could not find an answer
• I have searched existing issues and this is not a duplicate

Description

When launching the app fresh, the first time a Rive animation loads in a page, it shows blacked out sections where its semi-transparent png layers should be. Closing and opening the same page again shows it correctly.
Reproduced pretty consistently in all compilation modes (debug, profile, release)
Seems to not occur on IOS.

I have a feeling this is related to this: rive-app/rive-nitro-react-native#409

I am not currently authorized to upload screenshots, rive files or code because i am working on proprietary software.
