redisplay bug (visible in Gnus)?

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! Something strange happens in Gnus with some messages between the summary- and the article-buffer, when I scroll through the message. See <http://khaberz.net/xemacs.jpg> It only happens with some messages but I haven't figured out what these messages have in common. I can reproduce it with those messages. If there's any more useful info I can provide, please let me know. Thanks, Kai ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux zaphod 2.4.17 #3 Sat Jan 19 09:53:24 CET 2002 i586 unknown ./configure '--prefix=/usr/local/xemacs' '--error-checking=none' '--with-toolbars=no' '--with-mule=yes' '--pdump' '--without-msw' XEmacs 21.5-b4 "bamboo" configured for `i586-pc-linux'.
