  "message": "[metal] Use DemoteToHelper on Apple Silicon\n\nWhen per-sample shading is enabled, writes that occur after\ndiscard_fragment() are sometimes still visible on Apple Silicon. We\ncannot reliably detect when we are in per-sample shading mode, so just\nalways enable the DemoteToHelper transform until the bug is fixed in\nthe Apple driver.\n\nSuppress the new tests on Pixel 10 due to a bug in older OS versions.\n\nBug: 562093713\nChange-Id: I76f77372d7d5bc9a52d055cc099d2c2837d96daf\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/346995\nCommit-Queue: James Price \u003cjrprice@google.com\u003e\nReviewed-by: dan sinclair \u003cdsinclair@chromium.org\u003e\n",
