libreoffice 7 does not follow the system theme on MX23/KDE. I have tried several themes, but LO7 sticks to a win95-like (grey/blue) look and feel.
Other apps (KDE & GTK) behave as expected, and so does an AppImage version of LO6 !
I installed from the MX23 KDE RC3 ISO i had available, preserving a home folder, perhaps that has something to do ?
Note that the problem does not exist in a live session, so it may have to do with a setting from the preserved home, but which one ?
Previous versions of LO kept their config under ~/.librefoffice/x.y.z, but apparently not V7 ...

libreoffice theming can be set individually in its own settings. you can check under Tools->Options->Personalization if memory serves me correctly.

Tx, but that option is left by default, thus it should use the system theme. Let me illustrate:

LO7.4 (stock in MX23)

LO6.4 (AppImage)
As I said this is not happening from a live session nor for a new user test profile on the installed system. Hence probably related to migrating the profile. Since this is the only oddity i have noticed so far i don't want to re-install without keeping the home folder. I am no LO power user and can use the AppImage version anyway.

Can you check whether libreoffice-kf5 (kde frameworks 5 integration) package is installed?

bingo ! Installing libreoffice-kf5 solved the issue indeed, thanks ceeslans !
