Scaling TastyWorks for Ubuntu 20.04 w/ 4k laptop monitor
# Tastyworks is created using JavaFX, as discovered by glancing through
# their java library directory. JavaFX does scale for hi-dpi displays,
# but only does this automatically on Mac. To force this behavior on
# Ubuntu, manually set the legacy gnome scaling factor that is being
# used by JavaFX to detect this state, but I believe is being ignored
# by Gnome itself. [https://stackoverflow.com/a/26184471]
gsettings set org.gnome.desktop.interface scaling-factor 2
