Test to reproduce the issue var array = new Uint8ClampedArray(8); var imgdata = new window.ImageData(array, 1, 2); imgdata.data === array; This returns false in Safari and true in Firefox and Chrome. The spec says: > If source was given, then initialize the data attribute of imageData to source. — https://html.spec.whatwg.org/multipage/canvas.html#initialize-an-imagedata-object This makes Safari fail https://github.com/web-platform-tests/wpt/blob/7a0b0c285b91a0b1fa08da58c964b82e5cf40733/html/canvas/element/pixel-manipulation/2d.imageData.object.ctor.array.html#L28 https://wpt.fyi/results/html/canvas/element/pixel-manipulation/2d.imageData.object.ctor.array.html?label=experimental&label=master&aligned
