Mysterious additional login screen at startup

[romanb]

Thanks for the GDM tip - there are quite a few posts.
This one contains the solution to the issue.

What on earth is this?

A new day a new surprise. After entering the LUKS password (with vibration still), The next screen appears for a second before the the login page comes on. [image] Where is this page hiding itself and how does it appear when booting the phone? Thank you all!
