This problem was observed only on mobile Safari (ios 6.1) and not on desktop Safari or Chrome. Example of creating and attaching a canvas element in a way that it will not render: var doc = document.implementation.createHTMLDocument('test'); doc.body.innerHTML = '<canvas></canvas>'; document.body.appendChild(doc.body.childNodes[0]); See attached reduction for a test that renders something. 1885944 1 ahmad.saleem792 2022-07-22 04:36:46 -0700 I am unable to reproduce this bug on iPhone 13 Pro Max (iOS 15.6) and loading the reduction does show triangle same as desktop.
