This was mostly addressed by bug 1686244. What remains is mostly cs_clip_rectangle overhead.

Comment 5

[Lee Salzman [:lsalzman]]

The biggest remaining overheads are because of the brush repetition in the radial gradient causing it to use the slower radial gradient path, and also cs_clip_box_shadow, now that bug 1682194 has landed.

Most of the addressable slow-downs from repeat sampling and gradients have been addressed by now. Closing this bug out in favor of leaving other bugs open that better exercise potential remaining bottlenecks in this case.
