SYMPTOMS

• Typing becomes slow, everywhere
• Eventually, you can't type anymore (although cursor remains responsive, and RAM and CPU are not exhausted yet).
• Input methods disappear from the list (e.g. Japanese when Super+Space).
• .ibus-daemon-real shows abnormal use of RAM and CPU (see screenshots).
• X shows abnormal use of RAM (see screenshots)
• ibus-daemon-real disappears from the list of running processes.

STEPS TO REPRODUCE

I haven't found reproducers myself (see ADDITIONAL INFORMATION for a possible way to reproduce).

The times I experienced this problem I was typing on Emacs, DrRacket or Inkscape (other daily tools open, though).


WORKAROUND

Restart ibus:

ibus-daemon -dxr
