Skia Gold render comparison for CL 8223545

2026-08-09Pixel 6a hardware renders CL 8223545 patchset 2 EdgeToEdgeLayoutViewTest, revision 1 → 2

Why the bot is red

CL 8223545 intentionally changes how EdgeToEdgeBaseLayout paints system bar colors over display cutout insets, so the render test revision was bumped from 1 to 2. The revision bump renames every golden in EdgeToEdgeLayoutViewTest, which makes all five images untriaged in Gold, and untriaged images fail the tryjob until approved.

To verify nothing regressed, all five tests were rendered twice on the same Pixel 6a: once from the patched branch and once from a clean origin/main build, then pixel-diffed locally.

4 of 5 renders are pixel-identical to origin/main; they fail only because of the rename.
1 render changed, in exactly the intended region: the 75x100 px cutout-overlap rectangle inside the status bar (bbox=(1005,0,1080,100), 7,500 of 2,592,000 pixels, 0.29%).

The changed golden: top_left_sys_bars_right_cutout

Status bar color covers the overlapping cutout inset

Old: the red status bar stopped at the cutout, leaving a detached black square at the top-right corner. New: the red status bar spans the full width; the cutout stays black only beside the fitted gray content below the bar.

CHANGED 0.29%

Old render: black cutout square interrupts the red status bar at the top-right

New render: red status bar spans the full width over the cutout inset

Diff: only the 75 by 100 pixel cutout overlap region highlighted

Magnified old corner with detached black square in the status bar — Old, top-right corner magnified

Magnified new corner with continuous red status bar — New, top-right corner magnified

The four unchanged goldens

Each pair below is byte-for-byte identical between origin/main and the patched build (diff bounding box: none). They only need re-triage because the revision bump renamed them.

bottom_nav_bar

IDENTICAL

bottom_nav_bar diff, no highlighted pixels

left_nav_Bar

IDENTICAL

left_nav_Bar diff, no highlighted pixels

top_bottom_ime

IDENTICAL

top_bottom_ime diff, no highlighted pixels

fullscreen_when_tappable

IDENTICAL

fullscreen_when_tappable diff, no highlighted pixels

Method

Both runs used the same device (Pixel 6a, Android 16) and the same test invocation of chrome_public_unit_test_apk with filter EdgeToEdgeLayoutViewTest.*.
Old renders come from a clean origin/main build (ea38d3614964f); new renders from origin/main plus CL 8223545.
Diff overlays dim the new render and mark every differing pixel in magenta; raw numbers are in meta.json.
