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!!!
Can we see some screenshots? It's hard to work just with someone's idea of "better". Not to mention that font rendering can be tweaked on both Windows and Linux and we don't know what settings you've changed so far. Oh and I hope you're comparing the same font otherwise there isn't much point you the comparison.
And also show
ls -l /etc/fonts/conf.d
here you go on pastebin.com
I tried to upload a screenshot when creating this post, but it seems there is an issue with the instance I'm on, so I just tried uploading it to Imgur instead so here you go, and oh scaling is set to 1x (there is only 1x which is the default and 2x which I tried today, but it made all the UI elements and text too big and yep I'm not using the same fonts for comparison and I don't think it is as simple to install and use the font used by win 10 and/or 11, and honestly I do not know if using Microsoft font going to fix this issue or not
screenshot these all are the default settings except maybe for Hinting
The biggest problem that I see on this screenshot is that it is a compressed JPEG.
Lol blame linux mint, or is it imgur?
I don't know, however this is impossible to understand what's wrong with your fonts.
