On page "Thomas E. Kurtz" in English Wikipedia I made several edits using the visual editor, but when I asked for a preview it looks all wrong. I don't see any of my edits in the text and all of the text is highlighted with one of two different colors, some of it with light orange background, but most with a light blue background. Very strange, never seen this before.

More of the same bad visual diff behaviour in "John Tukey" in English Wikipedia. Description is same as report above.
Hi @Dough34, it must be some of wiki markup. Can you please attach a screenshot. It would really help.
