Description Ryan Haddad 2022-01-11 15:06:29 PST 
imported/w3c/web-platform-tests/css/css-transforms/perspective-transforms-equivalence.html is consistently failing on macOS arm64 bots with a very small pixel difference on the left edge of the displayed shape.

Comment 2 Ryan Haddad 2022-01-11 15:07:17 PST 
Based on when it started, this may be related to the custom pixel tolerance change in https://trac.webkit.org/changeset/287323/webkit
Comment 3 Simon Fraser (smfr) 2022-01-11 15:08:38 PST 
The test has <meta name="fuzzy" content="maxDifference=0-27;totalPixels=0-235"> so yeah
Comment 4 Simon Fraser (smfr) 2022-01-11 15:09:01 PST 
We get maxDifference=29; totalPixels=147
Comment 5 Ryan Haddad 2022-01-25 13:49:39 PST 
Marked test as failing in r288581.

This patch modifies the imported WPT tests. Please ensure that any changes on the tests (not coming from a WPT import) are exported to WPT. Please see https://trac.webkit.org/wiki/WPTExportProcess
Comment 8 Simon Fraser (smfr) 2022-02-09 09:30:14 PST 
Let the never-ending pixel tolerance tweaks continue!
