I reported something similar in Bug 50947, though there I couldn't type at all. Roan asked for JS console output there, so I guess that it would be useful here, too. This may also be browser-specific.
I'm seeing something very slightly different to this - see https://en.wikipedia.org/w/index.php?title=Wikipedia:VisualEditor/Feedback&oldid=563808463#Odd_bug_after_blanking_page If it matters I'm using Firefox 22 on Xubuntu Linux. I don't have another browser to test it in (Konqueror is apparently blacklisted from VE).
This is the same as bug 50947, I believe - merging. *** This bug has been marked as a duplicate of bug 50947 ***
