Client ignores scaling setting on Ubuntu 18.04.5 LTS

[germanicianus]

This is a known issue of Java which is especially a problem on small high resolution screens and detailed fonts like for traditional Chinese (zh_TW) because these are additionally blurred by the JavaFX anti-aliasing. The scaling can be fixed with the startup parameter -Dglass.gtk.uiScale=144%, setting it to the desired value. It would be nice to either have some documentation/mention of that or some obvious setting available to the average user.
