Thanks for your feedback.

So that is the "expected buggy behavior". The thing is just that Konsole tries
to keep all opened konsole windows running in the same process, which in turn
means all those konsole windows are shown on the same display(more precisely,
the display where the first konsole window opened through menu/icon/shortcut is
shown)

That "single process" model makes sense most of time, but clearly not when user
has specified the --display option. The logical behavior should be always
creating a new process to make sure the new konsole window are shown on the
specified dispaly.

Unfortunately, currently Konsole simply does not check and treat --display
option in a special way.  Actually there are  other Qt options which do not
work well with this "single process" model, like --session, --reverse,
--graphicssystem, etc. 

So to sum it up, this is a known issue. I will try to do something to improve
this situation in KDE SC 4.9 .
