Sorry, I'm well out of my depth here, but there we references to HiDPI which prompted my email. To my naive eye HiDPI appeared to be a temporary hack to get around the real problem of font scaling. So the logic was, if HiDPI is being talked about, then perhaps this area of the system may impac

Can I suggest that as this work is done you keep in mind (what I hope) is the long term objective to provide correct dpi scaling. e.g. a 10 point font should measure 10/72 of an inch regardless of the resolution or physical size of a monitor. I may (as an end user) want to then apply differen

Hi, Over at mutter we've been working towards supporting proper multi DPI setups when running GNOME using Wayland. Proper multi DPI means to support having multiple monitors where two or more monitors have significantly different DPI but applications showing correctly on both monitors at all times
