Bug Description
lsb_release -rd:
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Package: emacs24
Version: 24.3+1-2ubuntu1
Package: kde-window-manager
Version: 4:4.11.
I opened an emacs window and maximized it vertically. I then switched repeatedly between a "Customize Option" buffer and the *scratch* buffer. Every buffer switch caused the window to shrink slightly by moving the lower edge up. This continued until the window only contains only 2 lines of each buffer. No doubt the window manager is involved; I am using kwin (version above).
The output of "xwininfo -id 0x3000112" below shows the problem. Note that the height and corners fields change every time, but geometry changes every other time.

I would expect one of two behaviours. Option 1 would be to swap between two different window sizes, each containing the maximum number of lines for that buffer. Option 2 would be to keep the lower edge of the window at the bottom of the screen and absorb the difference in height by changing the size of some internal padding. Option 1 would be more consistent with the current resize behaviour.
This problem seems to be due to the change in height of the toolbar. If I disable the toolbar (menu-bar-
