Created attachment 162969 [details] Testcase Open the attached testcase and scroll so that at least two "tiles" of the background image are visible. On Chromium, once we hit the Skia's Image::drawPattern codepath we end up AWESOME resampling on every repaint which pretty much hangs the browser. The Safari port performs slightly better but not acceptably so. I originally hit this on an HP website for the Z620 but I imagine this is a common issue.
