AND, after a second or two, the screen switches back to the original window (e.g., t-bird). This tends to suggest something X-related. In my case I see instants of black screen on a Lenovo P50 with Fedora 24, using Intel graphics. Looks like a refresh problem, or maybe something related to switching the panel to the right gfx adapter (there is a dormant nvidia too, with nouveau blacklisted).
