Yast modules are shown in wrong size

Hello, I am using Tumbleweed and am having the following issue:
When I start Yast, the main screen is shown fullscreen which is something I like, the whole window including the surrounding frame is shown. I use Yast, as I use all the other programs, on the external 1920x1080 monitor. The laptop has a built-in screen with 2560x1600 dots.
But when I start a module, like for example Software Management, I see a window which is smaller than my screen but it is also taller. I can’t see the top menu. I can now drag the right side of the window onto my built-in laptop screen where I see the top bar of the window. There I can press the Max button and the window is shown full screen on my external screen.
I am using the built-in AMD GPU on Wayland.
How can I make the modules show complete, either full-screen or even smaller than that?
I only noticed this behavior in Yast, all other programs I use work well.
Here is some info about my computer:

Here is a screendump of the Yast software modue:

Thanks.

Is behavior the same when using Xorg instead of Wayland Plasma session? If it doesn’t improve, you may try disabling Plasma’s screen management by disabling auto start of KScreen 2 in background startup settings. Manual configuration can be facilitated using arandr installed from standard repos. Both arandr and kscreen2 employ the command line tool xrandr to do the work.

Inxi provides a commonly inadequate report of graphics using only -F option. Showing inxi -GSaz may be more helpful, as it also includes any kernel command line options that could affect graphics, in addition to other graphics details.

Yes, also in X11 the windows are the same size as in Wayland.
Sorry about the output from inxi, I am not that familiar with all the options available. Here is the one you mentioned:

I have now set kscreen2 to not start at boot. Will reboot and see what I get with xrandr.
