[BUG] Framer Motion Animation doesn't work on reload without delay

[KonerDev]

1. Read the FAQs 👇 ✅

2. Describe the bug

If I have two components that should be animated as soon as they are visible, they will not be animated when I reload the page with CTRL + R. Only when I reload the page with CTRL + SHIFT + R the animation appears.

3. IMPORTANT: Provide a CodeSandbox reproduction of the bug

Unfortunately I couldn't reproduce the bug in CodeSandbox because the reload mechanism seems to work differently there, but the bug is also there in Stackblitz. https://stackblitz.com/edit/vitejs-vite-cbkvjz?file=src%2FApp.jsx&terminal=dev

4. Steps to reproduce Steps to reproduce the behavior:

1. Open https://stackblitz.com/edit/vitejs-vite-cbkvjz?file=src%2FApp.jsx&terminal=dev and then https://vitejsvitecbkvjz-evfn--5173--d0228c83.local-credentialless.webcontainer.io (the second url is just the fullscreen version)
2. In the second url click on connect project after a few seconds
3. Press CTRL + R or click on the reload button of your browser
4. The animation doesn't really work

If you press CTRL + SHIFT + R, the animation will work fine.

5. Expected behavior

When I reload the page the animation should run normally, even without shift.

6. Video or screenshots

I'm observing something similar in our app. An animation plays if a route is freshly loaded, but sometimes won't play if I navigate between the route and some other route.

Will provide more information when I dig deeper. Sadly, I can't manage to reproduce it in a sandbox.

It's very difficult to reproduce the problem, but I just use a delay of 0.25, which at least temporarily solves the problem

My suspicion is that this is a bug in Chrome - specifically this one https://issues.chromium.org/issues/40887505

If you put an onUpdate on the animations you'll see the frames do fire, Chrome doesn't paint them.

For me it's also happening in FF and Safari.

These are my motion props:

initial={{ transform: 'scale(0)', opacity: 0.8 }}
animate={{ transform: 'scale(1)', opacity: [0.8, 1, 1, 0] }}
transition={{
  transform: { delay: 0.3, type: 'spring', stiffness: 300, damping: 15 },
  opacity: {
    delay: 0.3,
    duration: 2.2,
    times: [0, 0.13, 0.95, 1],
    ease: 'easeInOut',
  },
}}

Until 11.0.10, the element would at least appear in the DOM (without scale animating), and onUpdate was firing.

Starting with 11.0.11, onUpdate isn't firing at all.

Ahh ok thanks for the additional info - I'll take a look

Yes, that seems to be exactly my issue. Is there anything I can do to solve the problem temporarily other than a delay of 0.25 as it's not a nice solution to the problem. Is it possible to check whether the object has been painted and then start the animation?

EDIT: The error does not occur in Firefox
