Text Size Too Small

How do I increase Bisq text size? I did it before but since updating, text has become tiny & unreadable again.

O.S: Kubuntu 18.04.

Not sure if this helps: Text too small to read / see (Ubuntu) - #5 by MnM

gsettings set org.gnome.desktop.interface scaling-factor 2

I saw this, 2 is too big & 1 is too small, 1.5 returns an error from the console. I previously got the right commands from a forum but can’t find them now.
