The failure is appearing in the new scenario tests on simulator on intel mac that have Impeller enabled:

https://ci.chromium.org/ui/p/flutter/builders/prod/Mac%20Unopt/8237/overview

unfortunately, the failure is not causing the tests to fail. That is a separate issue.

Locally, I am also seeing the failure on an iOS simulator running iOS 15.4 on an arm64 mac. The screen is blank and the logs contain several messages like:

[VERBOSE-2:validation.cc(27)] Could not create render pipeline: Function solid_fill_fragment_main is using language version 3.0 which is incompatible with this OS.

Marking P2 since this will prevent enabling Impeller for customer: chalk.
