You are probably looking for a change made after 365067 (known good), but no later than 365075 (first known bad). CHANGELOG URL: https://chromium.googlesource.com/chromium/src/+log/e2ca0c18f40c746cafc2bb594bd5d8b06341cb1b..7f87dbd5a96f0e29039285544428b5298cb22aa2 Looks like fallout from d9ceaad90369f2840adfb88515298c816afb5c72 Does not repro with GPU rasterization.

Note: doesn't seem to occur when the stdDevation of the second feGaussianBlur is >= 0.53192309. (I'm sure this will seem significant in retrospect.)
