[Inferior 1 (process 28184) detached] Possible duplicates by query: bug 442399, bug 441561. Reported using DrKonqi
Not reproducible anymore in 21.12.1.
I don't think that this is fixed: The problem is here and this code is still like this in master: addRatioToComboBox(ratio(QGuiApplication::screenAt(QCursor::pos())->geometry().size()), i18n("This Screen")); QGuiApplication::screenAt() may return nullptr (https://doc.qt.io/qt-5/qguiapplication.html#screenAt). For me this happens happens on Wayland when I have at least two screens. It does not happen with just a single screen.
