Description Adam Roben (:aroben) 2009-12-11 14:03:55 PST 
To reproduce:

1. Go to http://webkit.org/blog-files/3d-transforms/perspective-by-example.html
2. Drag the slider left and right

The slider knob moves jerkily and lags behind the mouse. Notice that the transformed content above the slider animates smoothly while you do this.

The example should be updated to use oninput instead of onchange. I don't see the jerkiness or that it lags.

Whoops, I missed the platform reported. Reopening.
