Re: Family Tree Portraits glitching or not working
In Windows I would say it's a memory leak - but then it's Linux and I don;t think that would be applicable. The pictures you are having issues with are in one directory, each culture has one of those so you need to figure out the culture of the faction you are playing.
You could then unpack the files (there is a Linux thread about that), make game read the files (mod compatibility - yet another thread I think) and then edit those pictures or replace them.
The path to those pics: ...data\ui\[your culture here]\portraits\family
