Issue descriptionChrome Version : 53.0.2769.0 URL : http://codepen.io/joliss/pen/xOOWwd Browsers tested: Chrome (macOS, Windows): FAIL Firefox (macOS, Windows): OK Safari 9.1.1: OK Edge: FAIL When setting blur-radius on a box-shadow, the blur does not visually extend all the way through the blur-radius. This may be a peculiarity of the blur algorithm, but the result is that visually, the blur appears about half as wide as it should be. I created a CodePen that demonstrates this: http://codepen.io/joliss/pen/xOOWwd The CodePen shows the problem for inset box-shadows, but it seems to happen for normal box-shadows as well. I'm also attaching annotated screenshots on Chrome and Firefox.

Unclear if CSS or paint, needs further investigation.

The computed values for box-shadow are identical between Chrome and Firefox, this is a paint issue.

There's a spec issue here being resolved over on the other bug.

Issue 677689 is about filter:drop-shadow(...) not matching box-shadow - and so is the spec issue filed for it. (Granted fixing this would "fix" that in a sense, but...) Issue 179006 is a better dupe-target I think. |
