I started having this problem today, on Ubuntu 14.04. I reproduced this problem by selecting a profile with a smaller font size in the first split window.
Disabling 'Window geometry hints' worked for me. For people like me who are unsure how to disable it:
Right click in Terminator and select Preferences
Under the Global tab, the third option is "Window geometry hints".
Unselect the checkbox and click close.
