macOS on a low dpi screen is mostly full of those kind of issues. I wouldn't recommend using a low dpi screen.

The problem appeared in the screenshots that the article shows, I don't think it has anything to do with the screen.

It's a screenshot of macOS running in low-dpi mode.

One of my favourite unreported MacOS issues comes from how, at some point, they changed the appearance of the window close button to be a particular shade of red with a tiny little X in the center. And if you happen to be using a particular kind of screen and possibly wearing glasses, that little X kind of wanders around in the button, appearing just slightly off center in a maddening way. Made only more maddening by…

This is not a software bug, but rather an optical phenomenon called "chromatic aberration". What's happening is that your glasses are bending light at different angles depending on the wavelength, to the red and blue and green are landing at slightly different places on your retina.

It's a hard problem to solve optically and requires specially shaped lens. It's a common issue in telescopes, with higher end expensive scopes having these specially shaped lenses to reduce this effect.

My bet is on a random bitflip more than an actual bug in the code, based on its localised nature and rarity. Antialiased text always looks blurry to me after looking at pixel fonts all the time.

A bet on cosmic rays is a rare bet indeed ;)

I’ve used fullhd imac/osx for many years until around 2018 and never noticed anything like that. Easier to call it “low dpi issues” now that they destroyed it, I guess ;)

My bet would be on some compounding error from long usage also. I'm using Apple Notes and it fails in some random ways after keeping it open for 1-2 weeks: When I try to copy something I select, it copies some random stuff, dragging text won't work, I can check/uncheck todo boxes. Goes away when I restart it.

Notes has been super buggy for a while. The failure modes are so weird I don't even understand how it's possible for a text editor. E.g. text and selections rendered floating between or on top of lines of text. I wonder how they manage to bork it so hard.

Haha, off-by-one pixel error! I still see MacOS as the best choice for my desktop/laptop uses (browser and SSH), but I also have a documents folder that I’ve accumulated over decades. I still use various .txt files in the docs folder as my low tech note taking apps. I use the Spotlight or Alfred keyboard shortcuts (that also use spotlight index?) for quickly opening the files when needed - and annoyingly my most impo…

Funnily enough a simple fgrep is super fast on SSDs and actually reliable. Even across TBs of data.

With Spotlight you can never be sure. And to be fair, the Windows equivalent sucks just as much.

from the comment:

> That post points out it’s probably just subpixel stuff causing the issue, but I think my thick, cheap glasses at the time were adding a layer of chromatic aberration to something that was already visually confusing.
