[Webkit-unassigned] [Bug 142238] Extremely low performance layer compositing with Google Maps API v3

--- Comment #2 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
Safari 8 and Chrome have different compositing layer configurations for the map tiles. Chrome tiles are:

<div style="width: 256px; height: 256px; overflow: hidden; transform: translateZ(0px); position: absolute; left: 152px; top: 443px;"></div>

but Safari 8 gets:
<div style="width: 256px; height: 256px; position: absolute; left: 151px; top: 178px;"></div>

Note the lack of transform property.

(Another thing to note: Safari 8 still needs -webkit-transform).

If you fix that does the story change?
