On Linux, terminal glyphs were drawn with the browser's subpixel antialiasing, which leaves colour fringes on every edge. A new setting,
textRendering: grayscale | subpixel(defaultgrayscale), opens terminals with a greyscale glyph atlas and asks Chromium for full hinting at whole-pixel positions;subpixelis the previous look, untouched. It applies at the next start, likelocale, and the settings row is shown on Linux only: mac and Windows draw greyscale text already and are left as they were. Panes past the WebGL cap, which draw through the DOM renderer, come out identical to the WebGL panes at device pixels, and a frame-timing benchmark showed no difference between the two modes at 6, 12 and 18 streaming panes.
