Something in my system configuration changed that made this font unreadable, and I’m trying to figure out where it is getting pulled from so I can fix it.
The actual content of the files is fine, it’s just the tab titles and the sidebar content that is affected.
Unfortunately that doesn’t seem to be it; everywhere else that is using Sans seems to be doing it fine. Don’t have any user-level font-config, and what I see in /etc/fonts/ seems stock.
Maybe there’s something to get you started in this thread, from March 31st onwards. I know it doesn’t look like it at the start, skip the first bit (IYW).
I managed to change the size of the font (making it much smaller so I can get more info on my screen). I’m using Mint, so not a million miles away from Ubuntu…
I’m prob not the best person to ask though for help being a noob, there are wiser minds on this forum…
