I'm not sure if it's specific to Swiftkey, but I didn't notice this on the default Android keyboard.

I've relatively regularly seen Firefox lockups (in which the cursor will continue blinking, but Android will say "Nightly has stopped responding, do you want to wait or kill it") when I'm interacting with a number of text fields in Fennec. In particular, this morning I saw this on the Mozilla PTO app.

All I did was go from one input field to the next, entering data, and eventually my Nightly locked up. This happened twice in a row before I gave up and used the Android keyboard, so I hope it's at least somewhat reproducible.
Currently, the Android UI thread can block waiting on the Gecko thread when doing text editing, and UI thread blocking causes "App Not Responding" dialogs. I'm experimenting with moving the blocking operation to a background thread. This won't fix slow-downs, but at least the user can still interact with the UI, and Android won't complain about us hanging.
