New comment by sgn on void-packages repository https://github.com/void-linux/void-packages/issues/45306#issuecomment-1658362494 Comment: I think that's a bug with `syncplay`, `Qt.AA_DontUseNativeMenuBar` is a `Qt::ApplicationAttribute`, while `QWidget::setWindowFlags` expects `Qt::WindowFlags` The application should call `QtWidgets.QApplication.setAttribute(Qt.AA_DontUseNativeMenuBar)` instead.
