Apparently GetConfigOperation can retrieve a nullptr config, in which case we just need to retry until kscreen gives us something.
There are cases where the config is nullptr, ensure we're checking for this.
This quicksetting plugion allows the user to open the KScreen OSD which makes it easy to reconfigure a multiscreen setup. It's only available when more than one monitor is connected. Signed-off-by: Sebastian Kügler <sebas@kde.org>
