Can you tell why you think pixel-scroll-mode is the culprit, and not
those enhanced mode-lines? Why not ask the developers of those
mode-lines to take a look and find out why they make pixel-scroll-mode
so slow, as opposed to the default mode-line?
In any case, the profiles shown in these reports doesn't seem to point
to any problems with core facilities related to mode-line, so I'm
uncertain how to proceed with investigating this. Would it be
possible for you or someone else to come up with a recipe starting
from "emacs -Q" and loading as few 3rd-party packages as possible,
ideally none at all?
