Yes, it happens when CEF was not shutdown properly (application terminated) and when PersistSessionCookies set to True. It seems that Chromium tries to restore window but it doesn't work with CEF. And "--hide-crash-restore-bubble" which is now default doesn't help.

my app doesn't stores sessions. this is 100% not a window restore issue.
