Found a solution. Just set to a smaller font size then the problem is gone!!!
So, apparently, the panel is having problem to display "Your prersonal profile is connected to xxxxxxxx" (where xxxxxxxx is your VPN name) if it is too long.. As I mentioned before, it works ok on landscape mode and sometimes in other languages, but people here is having different results with the same landguage. So I suspected it is related to the string length of this message.
