Chrome does not have this issue. Steps to Reproduce: - Get an image from the same origin (header 'Access-Control-Allow-Origin: *' must not be present) - Wait for its load - Create CanvasPattern using the image - Fill the canvas with created pattern - Try to use canvas.toBlob() and it'll fail with 'operation is insecure' Example: https://jsfiddle.net/morethanwords/4u0L5gdn/54/ Temporary solution: draw the image to additional canvas and create the pattern using the canvas, instead of image. 1850887 1 webkit-bug-importer 2022-03-14 08:55:41 -0700 <rdar://problem/90248577>
