A brief update on some of the restyling performance work that we discussed when meeting last week in Paris:
There is Gecko performance work on restyling that should help with the performance issues while dragging the Firefox OS homescreen (at least until we have a way to connect touch events to OMT panning), and with issues that are encountered in Web content doing similar things (e.g., changing 'transform' on an element with a lot of descendants). This is now described in https://bugzilla.mozilla.org/show_bug.cgi?id=931668 . Second, there was a restyling performance issue right at the start of panning the homescreen. This is related to the CSS rules in gaia/apps/homescreen/style/{dragdrop,grid}.css that key off of the data-transitioning attribute, and needs to be fixed in gaia; BenWa described this problem in https://bugzilla.mozilla.org/show_bug.cgi?id=930587 . -David -- 𝄞 L.
