Hmm sadly, it doesn't seem to help.
$ env |grep QT
QT_SCREEN_SCALE_FACTORS=eDP1=2;DP1=1;HDMI1=1;DP2=1;HDMI2=1;
QT_QPA_PLATFORMTHEME=qt5ct
QT_AUTO_SCREEN_SCALE_FACTOR=0
I rebooted and set:
xrandr --output eDP1 --pos 5120x0 --auto \
--output DP1 --pos 0x0 --auto --scale 2x2
and applications Qt apps like wireshark and virtualbox are still
rendering with 2x scaling on both screens. (which looks normal on the
hidpi one, and small on the lowdpi one).
