[SOLVED] Bad font rendering and terminal cursor missing

[sicr0]

Hi

Google Docs documents have most line not rendered (the characters are there, I can select the text and paste it to a terminal to see it, but in the browser page it's invisible)
In Zoom a lot of characters are missing and I can't see the cursor (https://imgur.com/a/bNsRTIV)
I can't see the cursor in my terminal (Kitty)
In general the cursor works badly on Firefox, it doesn't correspond to the action that it should do or just disappears

These are the latest lines of my emerge.log: https://gist.github.com/ignamartinoli/8316f60729997fab7e2dc006fa3f5e32

I really have no idea what may have caused this.

Do somebody knows where could I begin searching for the problem?

EDIT:

I reversed the latest updates regarding Hyprland but it didn't work
