Hi all,
I ran into the exact same issue and found the following RDP weirdness
with Guacamole 1.1.0
Connecting to Windows 7 machines posed no issues.
Connecting to a Windows 2012R2 posed no issues.
Connecting to Windows 10 (1809) posed no issues.
However once I upgraded that particular windows 10 machine to 1903,
the issue began.
I tested both a physical and VM with same results. 1809 worked fine,
1903 gave the error.
Have a great day,
Andrew
