In this case is not a matter of privileges. It's a matter of 
configuration files that could have been messed up or set with the wrong 
perms. 

As root user is usually never called to run GUI based applications, 
root's configuration files use to be "clean" as if they have been 
installed from scratch. How I could say it? Root user is, in this regard, 
like a virgin user :-)

Yes, and you can use this fact to compare the permissions for the 
configuration files for the user where it works and the other where 
doesn't.

Look deeper inside at the "~/.config" folder and check out the 
permissions that hold the files of that two specific applications.
