Thanks for the tips, I will try it out. Since I can&#39;t reproduce it at will, I&#39;m not sure when I&#39;ll secure the redisplay traces.<br><br>&gt;&gt;    The place to start is in cedet/semantic/idle.el.  The outward<br>
&gt;&gt; call to the various work functions purposely does not use<br>&gt;&gt; &#39;save-excursion&#39; so tools like completion can move things around<br>&gt;&gt; for you.<br>&gt;<br>&gt; Or maybe I don&#39;t understand what he meant.<br>
<br>I have seen the undesired scrolling with global-semantic-idle-completions-mode disabled. Specifically, with these Semantic submodes:<br><br><span style="font-family:courier new,monospace">  (setq semantic-default-submodes &#39;(global-semantic-idle-scheduler-mode<br>
                                    global-semanticdb-minor-mode<br>                                    global-semantic-mru-bookmark-mode<br>                                    global-cedet-m3-minor-mode))</span><br><br>
