Is this a real flake? This is in pixel_test https://findit-for-me.appspot.com/ranked-flakes?flake_filter=test_type%3A%3Apixel_test
Yes, these flakes are real. Thank you for reporting them. They look identical to those reported in Issue 917040. Looking into them and categorizing them by which machine failed the tests.
