That's probably because Ubuntu 21.04 used Wayland by default for all but Nvidia [0] and 22.04 enabled it for Nvidia [1], and Wayland's fractional scaling is an ugly hack (both in how it's implemented and how it looks) [2][3]. Progress is being made [4], but it's quite slow. Switch to the X session on the login screen and you should have good scaling again (also, lots of applications that do screen sharing, like Zoom, do not work on Wayland [5]). Or just be like me and use Mint, which has no plans for Wayland support and you don't have to think about any of this.
