Issue description
Example URL:
Steps to reproduce the problem:
1. Visit a page that has code like
<html>
<head>
<title>box-shadow test</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=2.0" />
<style type="text/css">
.container {
box-shadow: inset 10px 0 0 #000;
padding: 60px;
}
ul {
margin: 1px;
}
ul li {
display: inline;
}
</style>
</head>
<body>
<ul>
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
<li>item 4</li>
<li>item 5</li>
<li>item 6</li>
</ul>
<div class="container">
<button>Button</button>
</div>
</body>
</html>
2. View the page on a android on a device with a retina screen. (Tested on Nexus 5X and 6P)
What is the expected behavior?
No line should be shown under the button.
What went wrong?
There is a thin line under the button.
Does it occur on multiple sites: Yes
Is it a problem with a plugin? N/A
Did this work before? N/A
Does this work in other browsers? Yes
Chrome version: 51.0.2704.81 Channel: n/a
OS Version: 6.0.1
Flash Version:
It seems to bleeds from the box-shadow if there is an object above the box-shadow that re-adjusts the render somehow?
Works as expected on Firefox for Android.
Unable to reproduce on a Mac with a retina screen.

Present in M52 also. Who do we assign these Android only paint bugs to? This is the second one and I have no idea who is best paced to look into them. In particular, who even has all the insight into what is different about the Android graphics pipeline.

schenney, does this reproduce if you remove the meta viewport? If not, then it may be a Ganesh bug.

No reproduction without the meta viewport tag. So assigning to Skia to see what they can do. Can we dump SkPictures out of Android in any way?

Yes. You can use about:inspect?tracing to connect remotely to trace android, and record frame viewer frames.
