pointcollection performance issue in chrome mac

I am working with a 100k+ point PointCollection. It performs very well when I first create it.

However, if I use points.removeAll() it will take 10 seconds (!!!) to remove the points. They all disappear at the same time after ~10s.

This happens in Chrome 45.0.2454.85 (64-bit) Mac OS but it is fine in Firefox/Safari.

Any idea why this is happening?


I’m seeing this problem too. We’ll have to look into what is going on.
