Bug#784123: vinagre: Grabs mouse and doesn't want to release it

I can see from gdb that Vinagre receives a window event via vinagre_window_state_event_cb that tells it the window is no longer in fullscreen mode. There was no preceding call to vinagre_window_toggle_fullscreen and I donât see any other calls to gtk_window_fullscreen/unfullscreen.

Setting GTK_DEBUG=updates appears to make the issue go away although it is clearly not a solution.

I use focus-mode set to âmouse' so that focus follow the mouse. Setting this back to the default of âclickâ appears to make this problem go away. Changing the setting back to âmouseâ and putting Vinagre back into full screen mode immediately exhibits the problem. Perhaps there is an incompatibility between focus follows mouse and full screen mode?

Dear Maintainer,
http://youtu.be/_Gf5XQkSd8Y
This video shows a full screen VNC session using vinagre on Debian
8.6. "At some point" mouse control is lost. Clicking icons in the
remote windows VNC session no longer works. Clicking on the terminal
on the left brings up the Linux terminal used to launch
vinagre. Leaving full screen with F11 reveals the Linux context menu
is selected on the desktop behind the VNC session and mouse control is
lost on the Gnome desktop until hitting Alt-Tab.
It seems non-deterministic as to just how the situation occurs. Using
Super-PageUp and Super-PageDown, Alt-Tab and switching in and out of
full screen with F11 are probably the best way to reproduce
this. Sometimes it seems stable for a while then things stop working.
There are also error messages reported by both vinagre and gnome-shell
(vinagre:13166): GLib-CRITICAL **: Source ID 630 was not found when attempting to remove it
current session already has an ibus-daemon.
