I don't see it anymore either. If you want to close it I suspect it's gone. If I see it again I'll certainly reopen it. Unfortunately, it has been so long that I may not be remembering about something with the reproduction context. I do remember it was browser windows and not browser tabs that did it, and that I was running at least one video when it was flashing. My apologies for the hiatus. I was trying to keep a good job (and I so far have succeeded).
