Details

Filing this bug for these 3 Firefox-only test failures (currently listed on https://foolip.github.io/ad-hoc-wpt-results-analysis/firefox-lone-failures.html ):

  1. https://wpt.fyi/results/css/css-backgrounds/background-attachment-local/attachment-local-clipping-image-1.html
  2. https://wpt.fyi/results/css/css-backgrounds/background-attachment-local/attachment-local-clipping-image-2.html
  3. https://wpt.fyi/results/css/css-backgrounds/background-attachment-local/attachment-local-clipping-image-3.html

For all three of these, the failure screenshot looks the same, and it's a subtle not-user-visible difference -- it's a rounding difference (+/- 1) in one or two color channels along the antialiased fringe of the the Test text that's shown in the testcase & reference case.

Severity: normal → S3
