No, this is a thing where the text is honest to God blurry on non-4K displays. The macOS version of Zed on a low DPI display has the worst font rendering of any application I've ever seen, and I used desktop Linux twenty years ago.
It's like they're rendering a high resolution font at low resolution using the simplest possible algorithm without lining it up with the pixel grid. It's very fuzzy. Characters have this weird sort of additive color intensity where strokes intersect that reminds me of Geometry Wars. It's broken.
They are working on it; the Windows build has decent rendering, and apparently the Linux version substantially improved recently. But they haven't gotten to macOS quite yet. I've been checking in on Zed every few weeks since it went public waiting for a fix.
