To reproduce: 1) start spicy, connect to a guest 2) Turn auto grab keyb on 3) move mouse out of and into spice-widget window, notice all is fine 4) ensure auto grab keyb is off, to work around Bug 40043 5) Shift+F11 to go fullscreen, again to leave, repeat a couple of times 6) turn auto grab keyb on, this only happens when it is on (and after switching to fullscreen a couple of times, or at least once) 7) move mouse out of and into spice-widget window, notice white flashes
I don't think this is happening anymore, and was probably a driver bug. Feel free to correct me.
