Small fonts on external screen with Qt5.

Small fonts on laptop using Qt5. So it seems tied to Primary switch as
to which screen it scales for. Fortunately when using dual monitors I
basically never use virtualbox, wireshark or nvim-qt on the laptop screen.
Incidentally if no primary switch is used the eDP1 becomes primary.
As far as I understand, QT_SCREEN_SCALE_FACTORS needs an entry for each
screen. The primary screen will get the first factor, then second screen
the second factor, so you can try this:
QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCREEN_SCALE_FACTORS="2;2"
