Created attachment 8615941 [details] Jaggy icon position - video Steps to reproduce 1. Move an icon while in Edit mode on the homescreen Results You can see some frames skipped while the icon moves. From a device which can render some WebGL games at 60 fps on B2G, observing recurrent frame drops on the homescreen can hurt the user's impression of smoothness. See attached video for details.

This seems like a regression to me, I'm certain it wasn't this bad before, at least not on a Flame... Likelihood the background colour fade is killing performance here. New homescreen is superior in this regard at the moment (and hopefully we can keep it that way).
Mass update: Resolve wontfix all issues with legacy homescreens. As of 2.6 we have a new homescreen and having these issues open is confusing. All issues will block bug 1231115 so we can use that to re-visit any of these if needed.
