Description Blazer Silving 2025-11-30 17:12:00 UTC 
SUMMARY
When disconnecting and reconnecting to the same krfb instance, the frames do not update further. Interaction from client to server is possible, but the client screen does not receive new frames from the server until `krfb` is completely killed and relaunched. 

STEPS TO REPRODUCE
1. Configure and connect to krfb like normal
2. Disconnect the VNC client, then reconnect to the same krfb session.
3. The frames no longer reflect the current desktop, they are from the last connection. 
4. The application is now unusable until krfb is restarted. 

EXPECTED RESULT
VNC should be able to disconnect and reconnect repeatedly with no issue.
