Otherwise when we randomise the wallpaper order we will always get the
qDebug + ran twice
random_shuffle is removed in C++17, so maybe we can change to
std::shuffle(m_randomOrder.begin(), m_randomOrder.end(), rand);
Let's use KCoreAddons/KRandom?
These things don't happen there.
I think this is fine. Imo we can address the comments on master
Landed this on the 5.17 branch just now to make sure it gets in for Plasma 5.17.2.
