That type of thing has been happening to some (but not the Terapeak part). No specific resolutions I can recall.
For now you could go oldschool:

You could then try reverting to the classic SH view (link in upper right of new page), and hope the current glitch isn't still there (but reverting is one way - you have to request back into the new page again).
Finally, as always, you could try another browser and see if anything changes (I don't think that helped any of the others with the same issue, but it's an easy thing to try.)
