[Bug 1299759] Re: ibus daemon cpu use flares up briefly when editing in Gedit

I can confirm the same issues on a Lenovo Yoga 2 Pro running 15.04.
High load from ibus-daemon ibus-engine-simple ibus-x11 and gedit.  This
is _severe_ on a laptop and causes the fans to kick in.  In addition to
the high load (and associated temperature/fan noise), gedit actually
crashes.

Setting input method to "none" also does not help.

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:
