I don't know if it's already reported but from the first MIUI 13 (Stable or Weekly [22.1.13]) there always a display/fonts/zoom bugs on Mi11 Venus.
All scale / icons / size are oversized in comparaison to 12.5, so by changing DP values in dev settings and put 480 (instead 411) we can retrieve the same display
like 12.5. Great ? No...
Unfortunately each time you reboot System, MIUI don't save / charge previous / choosen settings in dev settings, and even don't save the change size/zoom settings from Settings > Display.
Could you look arround this, the bug is easy to reproduce, Thanks !
