We plan to enable coalescing mousemove in Firefox Nightly builds within the next few days. With this enabled, we will coalesce all mousemove events to one per refresh driver tick. It is to reduce the cost of processing unnecessary mousemove events that have no visual effect to the users.
Related Bugs: Bug 1392876 - Enable coalescing mouse events to be once per refresh cycle Bug 1361067 - coalesce mouse events to be once per refresh cycle (requestAnimationFrame, rAF) (preffed off) Link to standard: NA Platform coverage: All Target release: TBD. We'd like to see if this helps some use cases. If not, we'd keep this switch off for FF57. Preference behind which this is implemented: dom.event.coalesce_mouse_move Do other browser engines implement this? Google shipped it in chrome 60. Security & Privacy Concerns: None _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
