Thank you for the example. That shows exactly what I was talking about, so this issue is clearly (at least somewhat) a matter of taste. To my eyes, those VSCode samples look harsh, crudely pixelated like something out of the 1990s, while the Zed samples look like normal anti-aliased text.
Ahh, thanks for the explanation. I guess I was thrown off by the screenshot attached to that bug report upthread, where someone compared zed's rendering against completely non-anti-aliased text rendered by VS Code.
