I recently updated ubuntu to 15.10. After the update I couldn't see any text in Skype! I tried reinstalling it
sudo apt-get purge skype
Deleted the /home/username/.Skype folder
and reinstalled Skype but that didn't solve the problem.
As you can see from the image screenshot above, I can't event start it now as it is stuck on the Terms of Use window
I managed to login after restarting ubuntu but then it failed again
I solved this problem by switching from Unity to Gnome 3
