Thanks.
I confirmed that the Y position is shifted down a bit at first open after icon
theme was changed.
The left side of attached screenshot is the first open, the right side is the
second (and later) open.

The root cause of this bug is that popup->height() in KickerLib.popupPosition()
(kicker/libkicker/global.cpp in kdebase) does not reflect the newly selected
icon theme at first call.
It may occur not only in KMenu, but also in other popup menu.
But it seemed to require many and major changes to fix and is fairly beyond the
scope of maintenance.

Any idea for fix is welcome.
