QA → Verify Code → OK Veyon demo mode → is working :) There are still some issues when using the presentation mode, but I don't see them necessarily in the scope of this bug. My setting: primary node, replication node & 2 win 10 clients. I've got a few remarks: - If one of the user is LAdmin and the other is a student, the start of the presentation is not possible (no traceback). - If the presenter has a lower screen resolution, the "listener" gets the non-scaled screen in the left corner. This is OK but not documented. LAdmin could do this. (this might be the case in italc, too) - I would also recommend blocking notification on the Windows client since "der Benutzer root greift auf diesen Computer zu" is displayed multiple times which might be irritating. - Few times, I didn't succeed closing a presentation on the first try. Trying again, I succeeded. I measured the time until the red/ green icons were visible in the UMC. Starting a presentation red icon appears → ≤ 4s green icon appears → ≤ 9s Closing a presentation red icon appears → ≤ 3s green icon appears: 6s, 26s, 5.5s, 31s - Once both icons disappeared when closing the presentation and shortly after the green was visible again (and did not disappear until I tried again) - Once when starting the presentation only the green icon was visible. - The usernames (in the UMC) sometimes disappear when they are updated (not in the scope of this bug)

That is correct. I did not change the changelog entry anymore, but I appended the advisory.
