I would advise against pushing KF 5.20 and Qt 5.6 to stable.
Granted, two bug reports are not much, but given the scale of the
breakage (plasma, activities, randr), those who will be unlucky enough
to hit the issues both Reindl and I experienced, will have a
completely broken KDE desktop, with no fix or way to circumvent these
I got a little confused reading through your updates... are you saying that from an empty account
