This definitely seems like a raster issue. It does not reproduce with DevTools emulation on desktop.

Can repro on my N4 (but not on my Pixel).  If I disable gpu rasterization, the issue goes away.

Brian, can you triage this?

senorblanco@ could you please take a look?

I too can only repro this on Nexus4, not on Nexus 6P or desktop.

It's not the tessellating path renderer (if I disable that, it still repros).

In fact, if I disable all path renderers in GrPathRendererChain except the default, it still repros. (If I disable the default path renderer, it goes away, but much of the content goes away as well, so that doesn't tell us anything definitive. It *could* be the default path renderer, or not.)

Brian, could you take a look or do some further triage?
