Skia's Issue Tracker (bug.skia.org or skbug.com) is the primary bug database where we track all defect reports and feature requests.
When filing a new issue, please select the appropriate template, most likely “Defect report from user” or “Feature request”. Include an example fiddle or image. All issues will be triaged by our program manager and assigned to the appropriate functional team.
Skia bugs found in Chrome may be filed in the Chromium Tracker (crbug.com).
