Hi, I have written a program with Qt 6 on Debian 13. I moved the same code and recompile on Debian 12. Both use KDE but I see different GUI on the screen. Why? By the way I use; w.setWindowState(Qt::WindowFullScreen); in main.cpp Debian 12: Debian 13: Regards, Mucip:)

According to your screenshots on Debian 12 you are using KDE 5, Qt 5, and X11 and on Debian 13 you are using KDE 6, Qt 6, and Wayland. Besides the totally different versions of KDE and Qt, also the switch from X11 to Wayland can have a huge impact.

Qt 6.12 LTS is out! See what's new in the release blog

Same code different GUI?

You can pass the style you want to use by command line ( https://doc.qt.io/qt-6/qapplication.html#QApplication-1 ) or by code ( https://doc.qt.io/qt-6/qapplication.html#setStyle )

@Christian-Ehrlicher ,
I added below line in main.cpp but nothing changed in Debian 12.
```
QApplication::setStyle(QStyleFactory::create("Fusion"));
MainWindow w;
```
