Very small "Style Preview" on new Kubuntu installation

Hello, so this is my first post here.

I recently decided to try Linux and installed Kubuntu. Now in LibreOffice Writer the preview for the styles is extremely small (even when compared to Windows 11).

My display scale is set to 125% and the preview in Writer changes to a usable size when the scale is set to 100%. But then the entire rest of my display is basically miniaturised.
(I also had to change the icon sizes in Writer to make them more readable)

Does anybody know any solution for this?

You chose a Word-like interface, aka a “tabbed” UI. Experiment first with the native “Standard Interface” and open the side style pane. The style preview is much better in the side pane because there is a lot more space.

PS: always mention LO version because of the differences between versions and platforms.
