It's clearly a bug.

No. Just because you expect something to be working doesn't mean that it is a
bug:

With display update in particular, there are a number of factors which go into
whether things will actually work, including the level of support within
FreeRDP and within Windows. Before jumping to opening a new issue in JIRA, it
would be much better to ask on the mailing lists for assistance, assuming you
are unable to progress forward with this on your own.
More generally, with any issue, rather than assume that any difficulties you
encounter are due to bugs, it is better to follow a logical path of
investigation. Remember that the more fundamental an issue is to the software,
the less likely it is that the issue is actually a bug (or other users would
have reported it). If something appears to clearly not be working as designed,
the most reasonable conclusion is that something has been misconfigured,
improperly set up, or is not supported in your specific configuration. Move
forward with that assumption, try to troubleshoot things on your end, and if
that fails approach the community on the mailing lists for further assistance.
It may ultimately become a bug, or it may not, but opening a new bug straight
off is premature.

If I click the F11 to go the full screen before the connection it take the
full screen but If I go the Full screen after the connection it shows black
screen in the background.

The only relation this behavior has with display update is that the display is
not being resized at all. The client side of Guacamole will always scale the
remote display to fit the available space. If the server side of Guacamole
resizes the display to fit, then that scaling will be 1:1. If not, then scaling
will be applied such that the entire display fits within the space given.

*If I reszie the browser proportionally ( height and width in the same
proportion ) then it's working fine. *
*But if I resize the browser unproportionally ( height and with in
different proportion ) then it's causing problems.* The height and width of
the windows is sent to the tunnel in the Guacamole.

This is still just Guacamole's normal scaling behavior - the same behavior you
would see for any application which scales a rectangular area to fit within
another rectangular area. If the aspect ratio of the browser is constantly the
same as the display, then it will consistently fit the available area without
gaps, but the display is still being scaled.

Please guide me where to post this issue to bring it to the mailing lists as I
don't know anything about the mailing lists.

I'm not sure how to advise here, as you've been posting new threads to the
mailing lists on a daily basis. Just send a new email to the user@ list as you
have been doing, opening the discussion on the issue you're encountering. The
community can then help you troubleshoot.
