I believe this is a duplicate of #41806

I noticed that issue is using 12.3.2-canary.43, not sure if it is Nextjs 13

That was just the version number of the canary available at the time, it still had all the same features as nextjs13, I've bumped the canary number I use to the latest.

It does sound/look like a duplicate of #41806, but I could reproduce this one locally on my Linux machine, while the other I couldn't. So it seems related but maybe not the same issue.

Closing as duplicate of https://github.com/vercel/next.js/issues/41806. I had a look at your reproduction and the problem is that you're rendering <Head> from next/head in the root layout, that should be <head>.
