--- Comment #5 from Martin <mschuet...@mailbox.org> --- Created attachment 157128 --> https://bugs.kde.org/attachment.cgi?id=157128&action=edit New crash information added by DrKonqi systemsettings (5.26.4) using Qt 5.15.7 Same problem as described in the previous comment. Furthermore, the window decorations of the stock Breeze theme do not work and a different theme is used automatically. -- Backtrace (Reduced): #4 0x00007f078d854e84 in KDecoration2::Decoration::shadow() const () from /lib64/libkdecorations2.so.5 #5 0x00007f078d3e2a55 in KDecoration2::Preview::PreviewItem::hoverLeaveEvent(QHoverEvent*) () from /usr/lib64/qt5/qml/org/kde/kwin/private/kdecoration/libkdecorationprivatedeclarative.so #6 0x00007f0803696d68 in QQuickItem::event(QEvent*) () from /lib64/libQt5Quick.so.5 #7 0x00007f0805faed12 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib64/libQt5Widgets.so.5 #8 0x00007f08052a8278 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib64/libQt5Core.so.5 -- You are receiving this mail because: You are watching all bug changes.
