How much anti-alias (rounded corners) increases visual quality on modern high DPI displays any case? As far as I understood, macOS dropped it for font rendering

  Here’s a simple demo of the difference: https://temp.chrismorgan.info/does-antialiasing-matter.svg https://temp.chrismorgan.info/does-antialiasing-matter.svg If the contrast is high enough (such as black on white), then I find the difference very clearly visible on my 2× Surface Book display, and subtle but definitely present at lower contrasts. You’ve got to get a lot higher than what’s available on the mass market now before you’ll want to drop antialiasing altogether. What macOS may have dropped is subpixel rendering—trebling probably-horizontal antialiasing precision by knowing the physical layout of subpixels. They won’t have dropped all antialiasing for font rendering, because that would be very visible. (Note: Firefox seems to be ruining the feColorMatrix, utterly misinterpreting alpha values above 1. This makes the greys disappear to white. And once I turn WebRender on, the second column doesn’t appear at all! I’d check for bug reports on Bugzilla and file one if I didn’t find one, but I should be in bed.)

    FYI there was no visible artifacts on my mobile phone on the page.
