That is sad news. I have a Linux Desktop that emits not so sharp text on my 1440p monitor. I always attributed to that bad text rendering to the low DPI monitor. I was hoping that one day I could buy a hidpi monitor that would make my Linux desktop as friendly to my eyes as my MacBook Pro. Looks like not anytime soon :-(
I meant that (imo) Windows's 'ClearType' hinting is sharp and easy to read at lower DPI-- Linux font rendering can be configured as 'hintslight' for MacOS-style blurry-but-preserving-font-shape, or 'hintfull' for MSWin-style aggressively-snap-to-grid-for-sharpness-and-legibility.
There is ofcourse more that can be misconfigured, but if you've got blurry fonts on Linux, there's a good chance changing the hintstyle to hintfull could tighten things up.
1. Other major vendors use subpixel rendering strategies to increase sharpness and legibility at reasonable DPI. MacOS eschews these strategies.
