Components: Blink>Paint
Re #c9 Yes. The alert I bisected in #c7 should not belong to this bug but was mistakenly grouped together.  Bug 838726  is the new home for the alerts that were mistakenly grouped into this bug.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/b63383e4e3f2b774ce0e6d3bfafb4adc84e48f2b

commit b63383e4e3f2b774ce0e6d3bfafb4adc84e48f2b
Author: Xianzhu Wang <wangxianzhu@chromium.org>
Date: Thu May 17 00:45:19 2018

[SPv175+] Force multiple chunks under subsequences

This increases stability of chunk ids under subsequences to reduce
full chunk invalidation because of chunk id changes. This especially
improves chunk id stability that was reduced by crrev.com/c/1027209.

This also helps to stabilize composited layer ids for SPv2, though
I need some more work for it (crbug.com/842356).

An example:
  Paint N-1:
  {
    ScopedPaintChunkProperties properties1(id1, same_properties);
    PaintBackground();
  }
  {
    ScopedPaintChunkProperties properties2(id2, same_properties);
    PaintForeground();
  }

  Paint N:
  {
    ScopedPaintChunkProperties properties2(id2, same_properties);
    PaintForeground();
  }

Previously, in Paint N-1, we combined both background and foreground
in chunk(id1), and in Paint N, we painted forground in chunk(id2).
Because the paint invalidator saw that chunk(id1) disappeared and
chunk(id2) appeared, it issued full chunk invalidation for
chunk(id1) and chunk(id2).

With this CL we'll force chunk for background and foreground, so
we'll issue chunk invalidation for the background only.

Measurements:
For all compositing and paint layout tests, this increases total
number of chunks from 3390 to 3676. (For comparison,
crrev.com/c/1027209 reduced the number from 4055 to 3390.)

Issue 839568 has been merged into this issue.

Comment 82 by wangxianzhu@chromium.org, May 22 2018

Labels: -M-68 M-69
Most of the regressions recovered, except:
- system_health.memory_mobile / memory:chrome:all_processes:reported_by_chrome:skia:effective_size_avg / load_search / load_search_taobao
- thread_times.key_mobile_sites_smooth / thread_GPU_cpu_time_per_frame / slashdot

The remaining ones will be fixed in M69 with a bigger refactoring/optimization of raster invalidation.
