Some applications do not properly handle fractional scaling after xrandr
, in my case I'm using Mate environment
$ cat /etc/X11/Xsession.d/45xrandr-custom
if [ "x$DESKTOP_SESSION" = "xmate" ] || [ "x$XDG_SESSION_DESKTOP" = "xmate" ]; then
/usr/bin/xrandr --output eDP-1 --scale 1.5x1.5 --brightness 0.7 --mode 1920x1080
fi
