The surprising thing there is the /occasional/ keystroke getting
through. That sounds like the app (or at least the input thread) is in a
loop, only occasionally polling for keystrokes.
You started kdevelop from the konsole session, and it was affected too?
That sounds like a shell job control thing. See the ctrl-z stuff below.
I'm basically stumped, but a couple more shots in the dark.
Running htop (or just plain top if you don't have htop) in a new
(responsive) konsole window, neither the almost dead konsole nor anything
else is sucking CPU cycles, right? If it's a loop, it should be, but...
Basic stuff but I'm grasping at straws, now: You haven't gone and done a
ctrl-z (shell-based suspend and return to prompt, type fg to restart the
process in the foreground again) or ctrl-s (old-school terminal scrolling
control, try ctrl-q to start it again), have you?
Other than that, I'm basically out of ideas.
