Fresh F26 install fully patched. Wireless shut off. Using a wired connection.

Randomly, I get a screen pop up that appears to be a browser display of .

I went to that URL and that's what it is, but it's popping up in it's own browser window, not Firefox or Chrome, both of which are on the box.

Randomly, this screen flashes and disappears in a second. Randomly, it stays up as long as I let it. Randomly it's full screen or shrunk to 1/8 of a screen.

I'd like to know if anyone else is seeing this and if anyone knows anything about it.

I tried numerous times to upload a screen shot of this in various formats and resolutions, but no luck. Just go tho the gnome site and you'll see what I'm seeing.
