From this point on, > holding down C-n shows this misbehavior. I cannot reproduce this, sorry, not with the above recipe. I tried different fonts and different sizes of them, and never saw anything like this. If in your case Emacs cannot keep up due to some high computational load (what does the CPU load say?), then I see no sign of that on my system when I scroll through NEWS. If you do see a significant CPU load, please tell (in a new bug report, see below) what kind of CPU do you have and whether the problem disappears if you reduce the keyboard auto-repeat rate. If you still see this after revision 113360 (where I made changes in the same function as in 113314, although I think they are unrelated), please report a new bug for this, as the problem you describe has nothing to do whatsoever with this bug. I will then try to give you instructions how to instrument line-move-partial and report the results.
