Git commit 79ce5dac9a2af0823c16f80dfff19ef3494d08c3 by David Edmundson.
Committed on 04/04/2019 at 01:03.
Pushed by davidedmundson into branch 'Plasma/5.15'.

Also unset QT_SCALE_FACTOR

Summary:
Qt scaling and kwin on X11 is never going to work so it is disabled.

However, Qt uses multiple environment variables for subtly different
internal things. We don't set QT_SCALE_FACTOR in Plasma, using different ones.

An XFCE user was setting this, which kinda makes sense if your DE doesn't
have an appropriate UI.

I don't think it's relevant for main_wayland as wl_output.scale should
trump the environment variable.

Use this instead: QT_SCREEN_SCALE_FACTORS

Why do you set this environment variable anyway?
