But I've just run across a severe case of presumably the same bug. It occurred while reading gnu-emacs-source from Gmane with Gnus. The article that shows the problem is at , and here's how to reproduce it: 1. emacs -Q 2. M-: (setq gnus-select-method '(nntp "news.gmane.org")) RET 3. M-x gnus RET 4. S s gmane.emacs.sources 5. RET 6. C-s M-e [ 187: Alf-Ivar Holm RET C-f RET, i.e., go to this article and open it. 7. In the *Article* buffer, click on the MIME part header [2. Displaying ISO week in calendar, updated for emacs 22, 2nd try --- application/emacs-lisp; calendar-hack.el]. You'll see that the entire text of the attachment has mouse-face highlighting, and if you scroll over this part the incremental undrawing bug is apparent en masse. Now click the MIME part header again to close it, and either the entire header or the second line of will be double. Further clicking to open and close the MIME part increases the number of (parts of) headers displayed. Steve Berman
