Squares in custom g-code box

[boogieman 1]

I almost spent two days now figuring this out, but i don't know how to fix it.
The problem is i see squares instead of text in the custom g-code box. I run Cura 3.6 under ubuntu 16.4 with xfce window manager. 
If i start cura with admin rights i can see the text just fine.

Any ideas?

oh, wow. I've never seen it do that before (which is one of those things you never want to hear from any engineer I guess).

Could you share your logs? I don't think there is going to be anything in there that is usefull in there, but it's worth a shot.

It is a font (configuration) issue. The gcode boxes (try to) use the system-defined non-proportional font.

here they are. The cura.log is just a copy of both stderr and stdout, i guess.

What i forget to mention is that i tried to see the file accesses of both the user and root program run. But i couldnt find something promising with lsof so far.
I also tried strace which didn't work because it makes cura freeze. But i'm not experienced with strace so i don't know if you could give some valuable information. 

stdout.log

cura(shortened).log

I knew I had seen it before in an issue:

Well, that shows that my memory is rubish.

Finally, its solved! Thanks guys. This has shown the way and has lead me to

My Problem was somehow in the $HOME/.fonts folder. There were some monospace fonts (.ttf and .otf) of some older Powerline installation. I just got rid of the folder and now the squares in the GCode section are gone!
Powerline seems to work as before.

Same problem, sudo apt purge fonts-powerline fixes the problem.
