This couldn't be caused by my change which modified code that isn't run. However, this could be a real issue, either a driver bug or Skia sending uninit data to the driver. Assigning to this week's Skia GPU wrangler.

I can't seem to duplicate this on my Mac, and looking at the repro case it's very simple and shouldn't be generating this result. I'm re-running the fuzz on the bots, but my suspicion is that this is a driver bug.

This looks very similar to  bug 719162 .

piman@, would you agree that this is the same issue?

Agreed. Mac software rasterizer.
