i really don't feel like you should even take the native linux builds online but somebody has to shove it in valve's face before they do anything about it
I am actaully legitimately confused here with any need for 2003 fonts. like while I'm not on bazzite atm, just running with windows 10 fonts looks fine for CS: Source
windows partition. fonts folder. ctrl+a. ctrl+c. linux partition local fonts folder. ctrl+v. (of course, this requires you to have windows installed somewhere)
