Jetson TK1 - strange behavior with Text Entry item addition..?

Today I have added “English” to “Input source to use” section from Text Entry setting menu from system settings
and after that, strange thing is happening with my Jetson TK1…

Does anyone experience this kind of issue ever after adding Text Entry item…?
also the performance is quite reduced!

How can I make this back to normal…?
