Issue descriptionSteps to reproduce the problem: 1. Open http://projects.delimited.io/experiments/d3-threejs/ 2. Observe the glitchy behavior of the 3d transformed elements What is the expected behavior? The elements do not flash or disappear. What went wrong? This is a regression. The demo has worked for years in Chrome on Android. The demo works on desktop (mac os sierra) in Chrome, Firefox, Safari and Brave. It also works great on an iPad using Chrome, FireFox or Safari. It works in FireFox on android, but the performance of the JS is terrible. Hoping you can fix it! Did this work before? Yes Not sure - The regression happened in the last 6 months or so I would guess. Just noticed it. Does this work in other browsers? Yes Chrome version: 60.0.3112.116 Channel: n/a OS Version: 6.0.0;LG-H815 Flash Version: It does appear to be somewhat a function of the number of elements. I setup a link with 50 chart elements for comparison... http://projects.delimited.io/experiments/d3-threejs-50/ It does seem to help but does not eliminate the problem.

Unable to reproduce the issue using #60.0.3112.116 on Android 6.0.1: SM-J710F Build/MMB29K. No flashing or glitchy behavior is observed. Adding TE-NeedsTriageFromMTV label for triaging of the issue as we don't have #6.0.0; LG-H815 device with us. Thanks!!

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/8ec06d20a359f2a59527e309dce52df49c2d4ae5 commit 8ec06d20a359f2a59527e309dce52df49c2d4ae5 Author: Vladimir Levin <vmpstr@chromium.org> Date: Wed Oct 04 19:57:41 2017 cc: Update the approximate scale math to use rect bounds. This patch changes the approximate scale math to use rect bounds instead of a vector, which yields more accurate results. This means that if a layer is effectively shrunk after the transformation we won't use a larger scale which could have been the case with the scale math.
