Black screen with mouse on TTY2, normal KDE wayland session on TTY1?

Fedora 37 KDE with the proprietary nvidia driver from the website, not rpmfusion (it’s a tensorflow thing).

When i change to TTY2 there is a black screen with a working mouse pointer while the normal KDE wayland session is running on TTY1. The pointer doesn’t look like KDE’s but like Gnome’s or Xorg’s.
To be clear, it’s not a login prompt, it’s an entirely black screen with a mouse pointer.

What is the explanation for this?

Edit: I just noticed that before login in for the first time both TTYs are the SDDM login prompt.
