So it seems that the problem really is > updating of the window displays. I'm not sure. What you see is the result of Emacs updating the display, but you cannot know whether the changes to buffers according to your inputs happened while the display was outdated, or immediately prior to updating the display as result of your clicking. IOW, it could be that all your inputs are processed in one go when you click, and the display updated right after that. Or do you have evidence that the scenario I described did not in fact happen? > I'm fairly sure that the problem was introduced by a recent change in > Emacs because I didn't change anything else at the time when the problem > first occurred. Specifically, I did not change the window manager or > its configuration. It would be helpful if you could quantify "recent" to the best of your knowledge and records, if not bisect the trunk. Thanks in advance.
