Using the latest app version (2.44.0) under iOS (26.3.1a), I started to see this proto-app frame before the app’s UI renders. I had to be quick with my screenshots to nab it.

Anyone else seeing this?

Mar 22 2026 update: Solved, thanks to @LemUrun@pawb.social in the comments:

It’s default look of Liquid Glass app. Normally apps are loading too fast for it to be noticeable. I posted about it too, but later realised what it is.

I’m seeing it too. Only difference is I’m getting the light mode version

Also noticed this for a while and thought it was weird. Sometimes I‘m also briefly seeing the badge flash on the settings during startup.

Thanks! I updated the post with this info.

No problem and thanks.
