Setting the input method to "none" does not work here. Same 19% CPU
activity of ibus-daemon, fann running high. However, task-switching to
another application than gedit stops the ibus usage temporarily.

Title:
  ibus daemon cpu use flares up briefly when editing in Gedit

Status in “ibus” package in Ubuntu:
  Confirmed

Bug description:
  When resuming an edit in Gedit, the ibus daemon flares up, abusing the
  CPU for a short while.  This happens every time lately.  All that's
  needed is to switch windows back to Gedit and resume editing.  Then
  the CPU usage spikes for a moment before going back down.  I would
  expect that the correct behavir is for the CPU usage to stay low, no
  matter the activity in Gedit.

  top has the following, sometimes even higher use, but it's very hard
  to catch since it happens for only a moment:
