STR: 1) Open http://planet.mozilla.org/, let it load 2) Press Home/End to scroll to the start/bottom of the page Without APZ it's considerably smoother, but still far from perfect. I'm not sure if we want to block APZ on this.
(In reply to Benoit Girard (:BenWa) from comment #0) > I'm not sure if we want to block APZ on this. I'm leaning towards no, since routing keyboard input through APZ (the correct long-term solution) is nontrivial. If we really want to do a shorter-term fix we can make the home/end trigger smooth scrolling in APZ which should make it smooth. (I'm not entirely sure what it does now, but I assume it uses the layout's "AsyncScroll" code path which isn't really so async).
Maybe bug 1198966 could help here, but I'm not sure.
