Michael Jumper commented on GUACAMOLE-414:
------------------------------------------

Mouse control still works absolutely fine for me: https://youtu.be/q8nDq2TRMik

This is not using TLS / VeNCrypt. All I'm trying to show here is that there is 
nothing wrong with the render loop, nor is there something which makes 
Guacamole inherently incapable of handling this sort of load. It _should_ work 
fine.

The only commonality across the cases where this is failing is the use of TLS. 
Differences in rendering, use of mouse, particular applications, etc. are all 
independent of that and likely red herrings.

> Certain VNC servers result in disconnection due to TLS errors

> Connecting to certain VNC servers such as Ubuntu Desktop (all versions I have 
> ever run) and a CentOS based Browser Docker 
> ([https://hub.docker.com/r/consol/centos-xfce-vnc/]) cause frequent TLS 
> errors and consequently disconnections. The errors in the log are as follows:
> {noformat}
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error reading from TLS: The TLS 
> connection was non-properly terminated..
> Oct 12 14:54:59 2004ff6050af guacd[8440]: read (4: Interrupted system call)
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Error handling message from VNC 
> server.
> Oct 12 14:54:59 2004ff6050af guacd[8440]: Internal VNC client disconnected
