Have triple monitor setup, playing in middle monitor. 1920 X 1080 res and after dialog cut scene, the left and right boundaries are no longer caged-in and my cursor flows into my other monitors. Only work around is to go into settings and check the option off, save settings, then go back in and check the option on. Alt+tabbing doe snot seem to cause this issue for me at least, only the dialog or other cut scenes.
