I had the same problem as yours after installing some updates yesterday. You can shut down ibus intelligent pinyin and install fcitx-googlepinyin through apt-get.
In Regions and Languages > Manage Installed Languages -> Keyboard Input System change it to fcitx from ibus. Reboot.
Now you use Ctrl + Space to switch between input system instead of Super + Space. I don't know if googlepinyin has some other incompatibilities, but as far as I can see it doesn't have the problem ibus-libpinyin has that bothered us.
