Pixel-moving filter effects render incorrectly with rotation

Project Member Reported by senorblanco@chromium.org, Apr 25 2016

Issue description

Version: 50.0.2661.86 (Official Build) (64-bit)
OS: Linux (probably all)

What steps will reproduce the problem?
(1) Open the attached file.

What is the expected output?

Two identical green boxes blurred along their local X axes. The top one is rendered in software; the bottom on triggers a composited layer (and accelerated filters) via will-change: transform.

What do you see instead?

Top green box appears to be blurred along its parent's axis. Bottom one is correct.

bisect-builds spake thusly:

You are probably looking for a change made after 291046 (known good), but no later than 291048 (first known bad).
NOTE: There is a Blink roll in the range, you might also want to do a Blink bisect.

Probably my change to enable deferred CSS filters in https://chromium.googlesource.com/chromium/src/+/f5d750088fbc5c9f99b1b175adc3f705a22fed7c.
