Window management buttons are missing

Bug Description There are not any window controls in the top right

Steps to reproduce:

Kubuntu 24.04 Wayland session (have not checked Xorg session) installed from xtradeb repo

IMPORTANT - open VIA GUI, not terminal

if czkawka_gui is ran in a terminal the buttons are present, if you run via Alt+F2 or use the app menu there are no buttons (varies depending the the terminal session instance somehow?)
