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:
