Hi.
Could you check your system health check with memtest86 or gnome-disk-utility?
I checked my hardware - everything is fine. I was just wondering why the Korean text is so slow. I think it's a problem on my end in some software. Well, guys, as on your end, Korean works fine - everything is fine. I don't need Korean on my system, only for rare testing purposes.
So consider the problem solved. Thank you.
