But that one has been marked as resolved.

GUACAMOLE-421 was closed as invalid as it's not a bug - it's Guacamole
representing the VNC display exactly as the VNC server requested. The JIRA
issue we're on here was opened later as a feature request to allow Guacamole to
specifically support {{-ncache}} and re-interpret what the VNC server is
requesting in that light.

I can even watch a youtube video ... That is definitely not possible when
connecting from/to the same devices via Guacamole ...

It should be. I do this myself without issue.
If the VNC leg of the connection is going over the internet, then perhaps not
so much. If it's going over a private network, then guacd should do a decent
job recognizing the video-like content and switch over to lossy compression
with dynamic quality.
That all has nothing to do with {{-ncache}}, though.

> I would like Guacamole to support x11vnc's {{-ncache}} option.
> In my mind there are two possible ways to do this: either allowing users to
> crop out sections of the connection (they would still need to be persisted in
> the VNC client's memory, though this does save on network transmission to the
> Guacamole client); or allow users to scale the view by _width_ rather than
> _height_. The latter would implicitly hide the ncache space off-screen if the
> width of the screen matches that of the other screen, though it wouldn't work
> very well if they aren't the same.
