> The screenshots below show the issue best. Exact same computer and server. In one screenshot,
using RealVNC's viewer, it looks great; using Guacamole, it's covered with black splotches.
I'm not sure how to debug this as it's obviously not an issue with the connection or the VNC
server (I'm using UltraVNC) since the one viewer works fine, but let me know what information
you need to help figure out why this is happening.
> My VNC settings in Guacamole are nothing more that the minimum required (port, username,
password).
