> If the screen resolution and scaling is the same, and the operating system is the same, then you should get very consistent results across operating systems. Or so you'd think. On Linux Firefox, if you turn off system antialiasing using fontconfig, then glyph widths are quantized to integers. And due to a bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1732577 https://bugzilla.mozilla.org/show_bug.cgi?id=1732577), turning off hinting but keeping antialiasing on does the same thing. And I recall on Windows (Chrome?), if you zoom out a page until the text is really small, then the font stops shrinking when the zoom level decreases (causing text to take up more width than before).
