Hello,

I am trying to make an image pan & scan system. I have a slider that zooms the image (that can be dragged) and also a small map in the corner of the image (that can also be dragged). You can see a rough example here (sorry, I am not allowed to use the design, so it's not formatted): http://lighe.madetokill.com/test/test.html

My problem is that although it works great in firefox and opera, it stutters in chrome, safari and IE (it doesn't currently work in IE) at any zoom level except 100% (at 100% it's butter smooth).

What is the reason for webkit's poor performance? Am I implementing this wrong? I am basically changing the margin-left and margin-top properties of the image. I know this is fast enough since at 100% it's perfectly smooth. Would I be better off using canvas? I am trying to avoid flash (or any other plugins) if possible.

Also please note this is work in progress, there are other bugs except this, so do not bother with those :)

Thanks in advance!
