Hello,
I tried to connect to an UltraVNC Server running on Windows 11.
The connection works without issue.
But there are no screen updates anymore after the initial screen.
I am still able to interact with the server to send mouse and keyboard
inputs(which I can see with other clients).
Other VNC clients are able to connect and get screen updates.
I found an old issue describing problems with UltraVNC:
https://issues.apache.org/jira/browse/GUACAMOLE-340
I captured the connection between guacd and UltraVNC in Wireshark and can see
that UltraVNC sends screen updates to guacd.
I can also see that guacd is getting those updates and initiates the rendering
process.
But it only does the "draft" and "commit" phases, and it doesn't trigger any of
the worker threads.
Does anyone have a working connection to an UltraVNC Server?
With Regards,
Markus
