i could move the mouse around but the mouse clicks were not registering.
using ssh, logged in (took a little while) and noticed that the load was
12 or higher. running 'top', i saw a couple ibus related processes that
were taking up gigabytes of ram. indeed, even though i only had chrome
and a couple terminals open, the system had started using significant
swap space in addition to the 6 gigabytes of ram available to it.

i killed a couple of those massively bloated ibus processes and the system soon returned to normal. and mouse clicks started working again. 
 
can you guys do a code review of the ibus related code, to see if you can where the runaway resource utilization might be occurring. and possibly do some checks. at least log info that would help to identify/pinpoint what is going on. 

at the very least, have it monitor itself, in terms of resource
utilization and have it automatically restart/exit if the utilization
goes above a reasonable threshold. 2+ gigabytes used by one system
process is NOT reasonable..

  ibus-daemon hogging resources

Status in “ibus” package in Ubuntu:
  Confirmed

Bug description:
  At times, typing becomes very sluggish and I can see ibus-daemon
