Isn't this just (setq mouse-highlight nil) ? IOW, should we just document somehow that if you are using X forwarding, you might want to disable mouse highlighting? > But is it indeed the case that X traffic caused by mouse highlight is > the culprit here? Though, to be fair, we indeed don't yet have concrete data to back this analysis up. It's more of an educated guess, I suppose. But other than adding documentation, I'm not sure I see how we can make much more progress on this decade-old bug report.
