The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/692d8c95a4a76ff431b17ab760684aa3e4852d30 commit 692d8c95a4a76ff431b17ab760684aa3e4852d30 Author: Chris Harrelson <chrishtr@chromium.org> Date: Thu Nov 09 20:37:16 2017 Expand interest rect in GraphicsLayer space, adjusted for approximate layer scale. An earlier patch moved expansion of the interest rect to root space, but this doesn't work for non-linear transforms like perspective. The intent of the earlier patch was to account for layer scale when determining the amount to expand, with the intent to expand by a certain number of pixels in screen space, not layer space. This patch achieves the same result, but changing the expansion amount by the scale factor.

Would like to merge this to 63. It's very safe and avoids continuing an M62 regression to M63.
