The client display is automatically scaled to fit the available area, which
in this case is a special viewport replacement consisting of a div anchored
to the bottom of the browser window. The styling of that div is such that
it *should* take up the entire area.

I have been unable to reproduce what you're seeing thus far, testing with
both IE11 and Firefox 47, but I am able to manually cause the same effect
by altering the CSS using the browser's dev tools, setting the height of
that div to something small.

If something were causing that div to not have 100% height as defined in
the CSS (or were causing "100%" to mean something different), then that
could cause this issue. The code behind that viewport replacement is also
supposed to automatically adjust its height according to the available
space, so if those calculations are somehow failing in your case, that
could cause this as well.

If you're familiar with the use of your browser's dev tools, can you look
at the DOM and styles surrounding that div? It will have the CSS class

Worth knowing, but I am leaning away from this being specific to server
configuration, especially since you are seeing differentiating behavior
with respect to the browser. With the exception of a theming extension for
Guacamole, nothing on the server should affect how the client renders, let
alone in a way which is different on a per-browser basis.
