Package: kde-style-oxygen-qt4 Version: 4:5.3.2-3 Severity: normal When choosing the Oxygen style in systemsettings5 the style is not applied to Qt4 (non KDE, i.e. /usr/bin/oxygen-demo) applications. Symlinking/usr/lib/kde4/plugins/styles/oxygen.so into/usr/lib/x86_64-linux-gnu/qt4/plugins/styles/ solves the issue. Thanks
