Public bug reported:
Running Kupfer in a LXDE session served within a Crouton chroot.
It seems to have entered a defunct state (without any special events
having taken place) and it is impossible to kill.
Normally you could work around this, but unfortunately because of the
way Kupfer forces itself into a 'splash' foreground overlay on all
desktop ports, it actually causes its box to appear over everything else
which is impossible to remove and hence forces you to restart the
desktop session from scratch.
A window manager restart (openbox --restart) is not enough, it just
repaints the same box as a light grey overlay instead.
kill -9 cannot kill the process and it continues to be reported in ps
like this which I think means it's waiting on file io and is a zombie
process...
