| Fixed In Version: | spice-gtk-0.26-1.el6 | Doc Type: | Bug Fix | ||||
| Doc Text: |
Cause: race condition when spice-vdagent is started in the guest and the client connects to it
Consequence: if the 1st monitor was disabled, it could sometimes be wrongly reenabled after restarting spice-vdagentd
Fix: delay sending monitor configuration when an agent connects so that we get a chance to negociate client/agent capabilities first
Result: first display no longer gets wrongly reenabled
