I can repro on 50.0.2661.66 on my Moto X.  The bug is that the right side of the shadow is cut off and only the bottom third or so is visible.  Moreover, when I pinch zoom in, the size of the cut off part jitters erratically.  This shadow renders fine on iOS Safari.

Searching open bugs, this seems similar to  http://crbug.com/498848  ?  cc'ing folks involved in that issue.

Just noticed shadow for the last thumbnail (Dangerous Skies) is not even
rendered.

This would be dramatically easier to debug if there were a test case with a white background. labratmobi@, Can you host something like that, or give us a reduced test case?

It might be related to  http://crbug.com/498848 , but then I would expect to see entire rows/columns chopped off, not just a portion of the row/column. And there's no reason for that bug to be mobile dependent.

The page uses one box-shadow on the image, and another on the div containing the image and the title. The interaction between the two may be the issue.

here is the URL for white background colour https://labrat.mobi/white_7c613d12ef27de3a6f369578d171eee3.html

It does have 2 box shadows, one on main Div and other for the image. But it was reproducible with one box-shadow as well.

But you can easily play with Chrome dev tools using chrome://inspect

here is the reduced test case https://labrat.mobi/temp/shadow.html

I found what is causing the issue, "border-radius" is the culprit here. Hope it helps.

Thanks. I'll look into it as soon as I can. It's hard to say if we're not drawing due to clipping content, or simply drawing incorrectly.
Uploading the repro case so we have it locally.

Doesn't reproduce on a Nexus 5x. Closing as previously it seemed to reproduce everywhere.
