First of all, KDevelop does not open up any X connections, if you grep
the source code you'll notice that there's no X11 code in it at all.
This is all handled by Qt itself and KDevelop has no control over that.

But apparently Qt decided to create 19 X11 windows for each process, why
it does that I have no idea, maybe file a bugreport. But looking at the
above, I'd say plasma is a much bigger problem for you if you cannot
create new windows.
