Bug report

Describe the bug

The image component is only requesting the image in the original size on safari for some reason, the requested Url always looks like this http://localhost:3000/_next/image?url=%2Fitalian-fabric-dark-blue.jpg&w=3840&q=75.

Code:

export default function Home() {
  return (
    <div className="max-w-screen p-16">
      <Head>
        <title>Create Next App</title>
        <link rel="icon" href="/favicon.ico" />
      </Head>

      <main className="max-w-full max-h-full">
        <div className="relative">
          <Image
            src="/italian-fabric-dark-blue.jpg"
            width={3984}
            height={2656}
            alt=""
          />
        </div>
      </main>
    </div>
  )
}

html output:

<main class="max-w-full max-h-full">

    </div>
  </div>

and when adding the sizes attributes two images are requested at the same time http://localhost:3000/_next/image?url=%2Fitalian-fabric-dark-blue.jpg&w=3840&q=75 and http://localhost:3000/_next/image?url=%2Fitalian-fabric-dark-blue.jpg&w=640&q=75

Our production server is also crashing every time it is visited from a Safari browser (seems to happen more on iOS) and this error is logged

Killed
error Command failed with exit code 137.

To Reproduce

here is a minimal codeSandbox.

open the sandbox in Safari
open network tab
notice the image is loaded in the original size
add the sizes attribute the Image component
notice the image loaded twice in the network tab

Expected behaviour

The Image component should load the correct image like in other browsers

System information

OS: macOS 11.0.1
Browser Safari
Version of Next.js: 10.0.3
Version of Node.js: 14.15.0
Deployment: next start

I've been testing around and I've noticed a couple of things, of course all of this is only happening (in my case) in Safari.

first, the behaviour differs from one layout mode to another. for example, setting the layout prop to fill or responsive is causing the same image to be downloaded three times or sometimes more. but only the correct image size is shown in the image tag.

often this error is showing in the console

[Error: ENOENT: no such file or directory, unlink '/Users/elia/Desktop/playground/next-image/.next/cache/images/9G8LlgjhcAHaytCnfziyTyUqLsNnv7Z5zXhyNBUSJGw=/1606475905162.vSeS9FT7kbvQQwhM0jGQCyFkfczi+MxKPZHeoZNnkfQ=.webp'] {
  errno: -2,
  code: 'ENOENT',
  syscall: 'unlink',
  path: '/Users/elia/Desktop/playground/next-image/.next/cache/images/9G8LlgjhcAHaytCnfziyTyUqLsNnv7Z5zXhyNBUSJGw=/1606475905162.vSeS9FT7kbvQQwhM0jGQCyFkfczi+MxKPZHeoZNnkfQ=.webp'
}

setting the loading prop to eager seemed to solve the problem in all the test cases I have been playing around with, but not in the production code though!

Thank you very much for the time and effort 🙏

I am facing similar error messages and in this case no image is shown in the frontend. For me it happens on multiple browsers (Brave on iPadOS and Chrome and Firefox on Windows) and in develop-mode but most of all in a semi-busy production site hosted on Azure.

I am seeing this issue as well, also with no image being shown on the frontend as in @ericvrp's case. In my case I am getting a broken image in Safari 14.0.2 on macOS (11.1), as well as Safari on iPadOS, but the image displays in Safari on iOS as well as Firefox (83.0) on macOS.

It might be another version (resolution/format) of the image that you are seeing.

We're also running into this issue with Safari on macos. Requests to the next server when using next/image cause the image resizing process to fail on the first request and so images are not displayed, but subsequent requests seem to succeed. Seen on Safari 13.1.2 on macos 10.13.6 and Safari 14.0.3 on macos 11.2. Next.js 10.0.5 node 10.15.3

bryanMeneses · 2021-02-10T17:48:03Z

I am using Next.js 10.0.5 too and all my images that are using next/image are getting downloaded three times in Safari. Any idea how to fix this?

Currently if you have `sizes` set in `next/image`, the image will likely be downloaded multiple times (usually twice) on Safari (macOS and iOS): the correct size for the viewport, and the original size specified in `src`. Also make sure you have "Ignore Resource Cache" disabled in the Safari Devtools when trying to reproduce: ![CleanShot 2021-03-09 at 21 05 54@2x](https://user-images.githubusercontent.com/3676859/110476820-6399f180-811d-11eb-93ec-5b2482c87884.png) The root cause is the way Safari handles `<img>`'s attribute updates. Although React updates all the attributes one by one synchronously and programmatically, Safari will still try to fetch the resource immediately and won't wait for other DOM changes to be finished. That means if we set the following 3 attributes in this order: `src`, `srcSet`, `sizes`. Safari will fetch the image when `src` is set. And then once `srcSet` is there it will fetch the resource again based on it. And finally, when `sizes` is updated it might correct the resource URL again. So the fix here is simple: by just reordering those to `sizes`, `srcSet`, `src`, it will only load the image with the correct size only once: <img width="1498" alt="CleanShot 2021-03-09 at 21 05 30@2x" src="https://user-images.githubusercontent.com/3676859/110477852-a27c7700-811e-11eb-88dc-d6e7895f67bd.png"> Fixes #19478.
