This came to me directly from Rigo "I still think it has to do with some smooth scrolling that runs berserk. The screen behavior is like this. It starts slowly and accelerates. My nose was dropped on this again when I scrolled this long email and it tried to smoothly scroll. Smooth scrolling is all about rendering delays, isn't it?"
Based on this suggestion I resorted to Google. It seems as if this is already known upstream. Take your pick from these three: http://bugs.kde.org/show_bug.cgi?id=76082 http://bugs.kde.org/show_bug.cgi?id=168132 http://bugs.kde.org/show_bug.cgi?id=163626 The crux of the problem seems to be that Smooth scrolling behaviour can be enabled/disabled in Konqueror but that the setting doesn't apply to any other application using the khtmlpart. Such as kmail and akregator (and probably calendar). As far as I can tell there is no way of configuring this behaviour globally, which is a design flaw in itself. I suppose it is still possible that differences between machines are caused by differences between the different hardware and different drivers to support this behaviour but that's purely speculation on my part. The third link has a suggested work around at the end. I tried it and it made no difference. If anyone else wants to try it and report back that would be appreciated. In the short term the best we can do is probably for the people affected by this bug to add a comment to the kde report and hope we can persuade them to do something about it. 76082 seems to be where most of the activity is. I'm going to confirm this bug now based on the upstream reports and link it so we can track the activity.
