mesh

I do not think a seamlessly universally scalable UI is needed if it is not implemented from the beginning (it is work and sheer infinite bugfixing). Yes, some loss of visibility area is the price to pay to be able to play without pain. We have little options on that one. Making only one UI design optimized for the common resolution 1920x1080 with all readable text sizes +50 % would still not make playing your game on a TV possible (nice comfort feature or for consoles/tablets) but readable for people with bad eyesight (essential feature). Everyone with higher resolution screens can double a smaller resolution as they have enough pixels to make a decent looking output scaling. That just doesn't work with 1920x1080 good enough as the half is 960x520 which is quite :-( or you get a really blurry pasta
