Gradients have visible discrepancies across clip boundaries

Project Member Reported by enne@chromium.org, Aug 29 2014 Back to list

Issue description

Run ToT Chromium and open third_party/WebKit/fast/hidpi/gradient-with-scaled-ancestor.html.

Run Chrome with --enable-impl-side-painting and then again with --disable-impl-side-painting and compare.  There's a very obvious visual discrepancy in the gradient when impl-side painting is enabled.

This seems like a "playback with SkPicture and clip" vs "raster into SkCanvas directly" sort of bug.
