I'd say complain to the creators of the theme you're using and maybe they will convince us that it's our fault and not theirs. It works fine with the breeze style.

Hm, I tried to switch theme from Breeze to all kind of Mint-x-Themes or Adwaita, but no change. Also the Themes have subtitels such as "GTK3, GTK2, Xfwm4), so I guess, they don't apply to QT, which is the environment of Okular, correct?
And I also saw, that qgis looks a little bit odd too. So I guess it is an Qt-Issue. Qgis has version 5.15.10 active. Maybe I can tune the QT-Themes somehow?
Hm, maybe this helps`? Not sure: https://ubuntuhandbook.org/index.php/2020/11/change-qt5-apps-theme-look-native-ubuntu-20-04/
That means you're not actually changing the theme correctly. There are many kinds of themes: GTK themes, window decoration themes, icon themes, and so on. What you want is the QtWidgets application theme, otherwise known as a QStyle (technical name) or an "Application Style" (user-friendly name shown in KDE's System Settings app. You can install that app and change the theme there.
Hi, Nate, all right, thank you, I'll try that. Today I also testet this issue with MATE instead of XFCE and there everything looks fine.
