I can't speak to what the software running within your remote desktop might
be doing, but Guacamole does support arbitrarily-many static virtual
channels within RDP. Multiple pipe streams will be opened and handled at
the same time.

There are no errors in the GUACD ?
There are no errors in the way guacd is handling things here, with the
exception of the incorrect log level. If you suspect this might not be the
case, the first thing for you to do would be to eliminate Eltima as the
next most likely cause. I would suggest implementing two simple
proof-of-concept applications which stream over separate and
differently-named static channels within the RDP session. If this works,
then you have confirmed the problem must either be within Eltima or within
the RDP server.
