i have  multiple instances of ibus-x11 running simultaneously in Bionic
18.04. Up to 40% of CPU is used by them. Once i run htop, the processes
automatically  disappear a few seconds later and everything goes back to
normal. In fact, i run htop now after every boot to deal with the
problem. If i use System Activity (KDE) instead of htop, i see one
entry, systemd, using up to 40% of CPU. If i kill it from there, it will
reappear few minutes later.
