I tried different font settings in the font settings and it didn't improve much (font hinting, anti aliasing, custom DPI settings, different font size)
The font is the default one which is Ubuntu Regular with font size set to 10
Sub pixel order is set properly to RGB Linux Mint xfce
Even when running windows in a virtual machine, the font rendering in it is miles ahead of what I got on my Linux setup!!!
TBH I'm just following https://distrochooser.de/ #1 recommendation, I want something that works best for me, not willing to spend any more time in testing new things that might be good, if it is good then I will let the community try them 1st, I will be the last to jump in
