As stroke() is called iteratively, it sometimes uses older color values, despite `strokeStyle` being changed prior to the call. This has been documented with a code snippet on Stack Overflow: https://stackoverflow.com/questions/74050672/html5-canvas-context-does-not-update-in-safari It is also observed in a similar example by @Kaiido: https://jsfiddle.net/7awL4fg3/ This has been tested on a MacBook Pro with Apple Silicon, and several iPhones. It is present in Safari 16 and Safari Technology Preview. 1906019 1 ap 2022-10-16 18:59:56 -0700 Sounds like bug 245465 (please see its dupes for details). Please verify with a future Safari Technology Preview, once release notes say that it's beyond 254889@main. *** This bug has been marked as a duplicate of bug 245465 ***
