Note: qua-non was unable to reproduce this bug, but we wanted to post it here for future testing.

TextInput isn't working for me when I deploy it to my Android phone running SwiftKey. Instead of allowing me to enter and predict words, as SwiftKey does in other apps, each letter I enter overwrites the previous character. If I press the space key, it inserts a space, and the next enter shows up correctly. However, another letter after that will overwrite the previous one. Thus if I type 'hello world', I see the following in the display (one line per keypress):

h
e
l
l
o
o<space>
o w
o o
o r
o l
o d

Using the HTC Sense or default Android keyboard, I get expected behavior, so this is an interaction effect with SwiftKey. I've tested this on an Android 4.2.2 (AOKP) and a Android 4.3 (HTC Sense) device, both using Swiftkey 4.4.2.254. I'm also getting it using the Swiftkey 4.5 beta app.
