--- Comment #5 from Sebastian Kügler <sebas@kde.org> ---
I'm opening kcmshell5 kscreen, then "Scale display", set the factor to 1.2 and
hit OK on the popup.

From reading scalingconfig.cpp, you're only writing the scalefactor to
kdeglobals via KConfig and to xrdb.

For the kwayland backend to pick up the changes, which it then writes to the
kscreen hash config file, it needs to trigger a screen config change, which it
does after changing the config through output->setScale() and
SetConfigOperation.

Essentially, I haven't found the output->setScale(1.2) call anywhere in there,
the scaling doesn't go through kscreen API (and backend) at all.
