There's a bug in YoRHa skin with font starts appearing after a2451465 commit. Font is 'jumping' and there's more pixels on edges, seems like AA is off, but i'm not sure.
latest(and also on that commit):

on 9300 for example(before bump to qt 5.14):

P.S: it's not important to fix this, i'm just want to report about that.
Probably a Qt bug which means it might get fixed with some update.
It's possible to set text antialiasing in Qt but this would have to be done for the painter object which renders the text. Waiting for Qt to fix this sounds more sensible.

Looks like it doesn't appear on latest masters anymore, so i'll close this issue.
