Start with the reproducible command in scripts/benchmarks_ci.py, using the “Startup - PaintDotNet - FDD Publish*” filter, and compare the listed baseline and compare commits. Review the linked benchmark and test reports to determine whether the Windows/x64 startup regression is reproducible and what change accounts for it; done means the regression is explained and its status is recorded.
