OP - could you try this in today's Canary?

When I run it I see a jump in size at the end but not a blink.
FWIW, I have created the two Skia bugs:

skbug.com/7927 (GPU blur pops when sigma gets close to zero)
skbug.com/7928 (Discontinuity in GPU blur animation)
I tried on Canary, it's ok, no blink.
But i see the little jump in size like you.

Then, I retried with Chrome and I don't know why, but i can't reproduce the blink effect ( same Chrome version and same JSFiddle ).

Maybe it was due to an external cause ? Windows ? Hardware ? I don't know.

Thanks anyway
