Texture issue when rendered in Flutter

We have some weird texture issues in the images of our Rive animations. This issue does not come up when tested in Rive Preview: https://rive.app/preview. The issue comes up when the .riv file is rendered in Flutter.

Version of Flutter: 3.19.6

Version of Flutter Rive package: 0.13.2

Thanks for reporting this . You will pass this information to the development team.

Do I need to pass the information to the dev team, or will you pass it along? On another note, if the dev team needs more information, I can share the necessary details. My timezone is PST, and I can also jump on a quick call if needed.

Hi , I suspect this is an Impeller issue. Was this tested on iOS? When building for Flutter for iOS, the default renderer is Flutter's new Impeller renderer. The other platforms use Skia.

You can test this by forcing the renderer to be Skia. If you confirm that it looks fine with Skia, then you can try testing to see if the latest master version of Flutter solves the issue. The Flutter team is quite responsive to these issues and are continuously fixing inconsistencies between Skia and Impeller, so the problem may already be solved.

You can find more information in our docs on how to test this: https://rive.app/community/doc/overview/docD20dU9Rod#note-on-rendering-in-flutter

Thank you ! Just tested everything you recommended, and it's indeed only reproducible on iOS with Impeller enabled. I also updated to the new stable Flutter version (3.22.0), and the issue was resolved, no more texture glitches.
