The system comes to a crawl when SVG images are hovered over. There is clearly an inefficiency here. The issue may be that we are copying Cairo's path data each time we inspect it due to a limitation/our misuse of the Cairo path API.

I was looking for a good way to reproduce this. Is going to http://www.croczilla.com/svg/samples/chem1/chem1.svg, hovering the mouse over the circles, and measuring CPU usage a good metric?

Neither Alp's nor kov's example are present anymore. Can someone post an example as attachment to this bug?
