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

[Michael Neilly]

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 don’t 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 ‘mouse' so that focus follow the mouse. Setting this back to the default of ‘click’ appears to make this problem go away. Changing the setting back to ‘mouse’ 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?
