I just had Jitsi Desktop 2.10 installed, connecting to my own Openfire 4.2.1 with Openfire Meeting plugin.
I can see the other desktop however the quality is not workable. What I mean “workable” is by open Notepad on the source desktop. The shared image is very blurry and very hard to read the text of the Notepad. I been looking in the Option to find the setting for image quality.
The 2 clients are on the same subnet, however the Openfire server is remote via a slow link (average 10MB speed)
