Calibration profiles

Benchmark results depend on Chrome profile, OS, input device, and extension mode. Record these with every run:

  • OS and version
  • Chrome version
  • pi-chrome package version
  • companion extension version
  • trusted mode: off / auto / on
  • input hardware: trackpad vs detent mouse, touch support
  • permissions: clipboard, fullscreen, downloads
  • viewport size and deviceScaleFactor
  • loaded privacy/security extensions

Known environment-sensitive areas:

  • WebGL fingerprint can warn/fail in VMs, remote desktops, GPU-disabled Chrome.
  • Scroll momentum expects trackpad-like decay; detent mouse wheels may fail manually.
  • Touch tests require touch events enabled/supported.
  • Dialog/download/file-picker tests require native browser UI handling or manual intervention.
  • Stack traces vary across Chrome versions; tests should only fail concrete automation URLs/Runtime frames.
