I am seeking to up-scale a single application in Ubuntu 17.04, Gnome Shell 3.24.
In my concrete case, the motivation is unstable zoom functionality in Franz, but another reason could be older apps not designed for scaling to high resolution displays.
This answer from superuser suggests using this script to up-scale. The script, however, minimally allows up-scaling by a factor 2, which is far too much. The script also makes use of the
xrandr package, which is deemed obsolete by
Is there a hack that will allow me to up-scale a single application window to, say, 120% of the original?
