Login Screen broken

Hello, I am new to KDE Plasma and I have a Problem.

My Login Screen looks very broken (Picture attached)

The Lock screen (when i lock my Workstation) looks normal but the Login after boot is broken.

The Display on my Second Monitor works and also the Login Prompt is shown normaly on the Second Screen but on my Main Screen it looks like this:

I already tried to remove all Themes and use default. Also reset KDE Plasma to default settings did not work.

Once I’ve logged in everything looks normal

Does someone know how to fix this?

My System

Intel Core i5 7600k
NVIDIA Geforce RTX 3070 Ti
Fedora 38 Workstation KDE Plasma Spin

LG Ultra Gear Monitar as Main Screen
Acer s242HL as Second Screen

OK I pretty much fixed the Problem by setting default DisplayServer to x11 instead of wayland.

I did this in /usr/lib/sddm/sddm.conf.d/plasma-wayland.conf

But I am not sure if this is the correct Place to edit something like this.

Now my login Screen looks normal with one Issue remaining → The same is now Displayed on both of my Screens. But they are different Login Prompts, so it is not just a mirrored Version of my Main Screen but a second Login Prompt wich works the Same as the one on my Main Screen
