The above is typical and not isolated to that particular page. I think it is always the left-hand panel that goes blank. If i click on the place things SHOULD be the click is effective. It is just the visibility that is missing.

Refreshing the page sometimes, but rarely, works.
This is a somewhat new situation -- a month or so?
