I'm probably less picky than the author of the article, but issues I do notice are (in Linux, but since I only use it I don't know if they exist in other OSes too): -some websites render with a very strange font, that includes quote symbols '"' being very tiny, which I'm not sure if actually intended like that or a problem in linux specifically, and sometimes all letters being rendered in such ugly way to be hard to read -symbols in mathematical formulas (some types of arrow, ...) rendered as colored emoji, even if they shouldn't in that situation since it's not a chat program according to the unicode spec -sometimes unicode chars becoming a square box, even if having tons of fonts installed
