Git commit 4b2abc581c6b3e7a4c2f1f893d47fad5d3806aca by David Edmundson.
Committed on 22/11/2016 at 10:32.
Pushed by davidedmundson into branch 'Plasma/5.8'.

Disable Qt's high DPI scaling on shutdown/switch user dialogs

Summary:
They use Plasma's scaling, so in theory it should have absolutely no
effect.

In practice it has an effect of hitting a Qt bug with font rendering.
