Same for all values, except I get 364 instead of 368 for the last one.

18 in all cases.

Note that I use (setq line-height 0.1).

With a 0 value, toggle-frame-fullscreen does not have the problem
of the weird bottom margin.

The bug with C-c C-e in org-mode is still there when I fullscreened
through the window manager.

I get no error.

I investigated and here is the minimal config to reproduce the
problem:

(menu-bar-mode 0)
(tool-bar-mode 0)
(scroll-bar-mode 0)
(set-frame-font "Inconsolata 13")
(setq line-height 0.1)
(set-frame-parameter nil 'fullscreen 'fullboth)

;; Add Org export backend so that the export dispatch window
;; is big enough
(add-to-list 'load-path "~/install/git/org-mode/contrib/lisp/")
(require 'ox-rss)
(require 'ox-beamer)
(require 'ox-latex)
(require 'ox-odt)
(require 'ox-koma-letter)

Then from there, emacs -Q C-x C-f ~/test.org C-c C-e will
throw the error.

(You would need to download Org from orgmode.org to
get the contrib/lisp/ directory.)

And my screen resolution is 1366x768, if that helps.
