Keyboard input inconsistent

[karmameleon]

Sometimes keyboard works with input and sometimes a strange little intermediate interface pops up and translates. Would be nice if when tap on terminal (for example) keyboard pops up. Also how to completely disable the floating menu thing. Shown in lower right corner.

I got quite annoyed with it too
That is the SogouIME
I managed to stop it by replacing the files /opt/sogou/files/bin/sogouImeService and /opt/sogou/files/bin/sogouImeService-watchdog by empty sh files:

#!/bin/bash

EDIT: I've been noticing that sometimes the apps seems to 'freeze' the keys, but then i close and re-open the app and it fixes. Unsure if it's related
