Issue descriptionUserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.98 Safari/537.36 Steps to reproduce the problem: 1. Add CSS transition to change fill on hover for <svg> element 2. Hover multiple times in and out 3. Observe extra artefacts on SVG Test case here: https://jsfiddle.net/SamPotts/2w5Lhkdm/ What is the expected behavior? No artefacts added. What went wrong? Artefacts were added around the outside of SVGs. Did this work before? Yes Does this work in other browsers? Yes Chrome version: 54.0.2840.98 Channel: stable OS Version: OS X 10.11.6 Flash Version: Shockwave Flash 23.0 r0 I've also noticed in recent version some SVGs are no longer as crisp as they should be.

I can repro on ToT/Linux, but only with GPU rasterization turned on (--force-gpu-rasterization).

You are probably looking for a change made after 405376 (known good), but no later than 405387 (first known bad). CHANGELOG URL: https://chromium.googlesource.com/chromium/src/+log/625f7915702eac0c2aa90a7445100be2f67deffc..18fac5c4bf292cc711aee969b9a88f8d8630e861 Most likely https://chromium.googlesource.com/chromium/src/+/5ac42f32e7b4142cd578082424a85a26794cf0ab (Partial raster for GPU).

Does not reproduce with partial raster turned off.

This is very likely a duplicate of crbug.com/663701 For certain path drawing modes, Skia draws outside of the playback rect specified by CC (and relied upon by partial raster). Will bump the priority of that bug and block this bug on it.
