Comment 1 for bug 1880710

Thanks for the report Natalia, and for discarding the obvious suspicion that this might have been caused by a refresh in the background.

I understand this is the first time you're observing this problem?

Do you have extensions installed? (maybe an extension affecting google webapps was itself silently updated and requires a browser restart?)

Can you open the same URLs that won't render in a new tab, and do they render correctly there?
