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!!!
I wonder what someone has to do to have worse looking font rendering on Linux. I find the font rendering on Windows worse in every regard and inconsistent (size). On Linux I just set hinting to slight and anti-aliasing to greyscale and all my fonts look nice. Same font with same size on Windows (VSCode is the only program I use on both OS) looks slightly blurred; only the fact that my work display has a higher pixels density makes it ok for me.
Apparently nothing just get a 10 year old laptop and use Linux mint on it🤷♂️
