When creating profiles via API with noise.canvas.enabled=true, the canvas hash stays identical to the Chromium default (C387DD7E19F32ED3CBA04D0F7CA99421), regardless of seed value.
GUI "Auto noise" produces unique hashes. API does not.
Tested seeds: 0, 42, 1337, 9999, 1938537032 — all produce same default hash.
GUI-created profiles produce different hashes:
- Profile A:
882F6435CFC14BCFF7CAA6BEFEF1C22
- Profile B:
5F79A84F5255DB0097F1AB483CEA094B
