Morii, this topic sames to be related to same problem that this one: http://www.tuxguitar.com.ar/forum/5/1437/1-2-fingerboard-no-strings/

Lets post new comments in this one.

I'll say same as my last post in the other topic.

Try to open with any text editor the file:
~/.tuxguitar-1.2/config.properties

(if somebody don't knows.. ~/ means the user's home folder.. e.g: /home/[username]/ )

* It's important to edit this file when tuxguitar is closed.

And try append this line:
painter.force-os-defaults=true

Save the file, and run the application..
so does it fix something ?"
