Hey Kris - just pinging you to triage this Android bug

I can't reproduce this with webrender, but with webrender off this is very obvious. I'm a bit confused why Pixel3 would not be using webrender though or if webrender is affected by this as well sometimes.
@jnicol: do you have an idea what's going on here?

Couldn't webrender be disabled because of the experiment?
I too can very easily reproduce this with webrender disabled, but it runs perfectly with it enabled. In the non-webrender code, when we can't paint fast enough to keep up with scrolling, we paint at a lower resolution to make it faster. That's why it's blurry, until we catch up with the scroll. This is a great example of webrender beating layers \o/
I am slightly curious as to why the performance is so dreadful, but I'm not sure how high we want to prioritise issues that will be fixed by webrender.

The same issues are present on Fennec.
Jeff Boek: let us know if this is a high priority issue as we are currently mainly focusing on Webrender issues.

This page works correctly with webrender, which has now been shipping everywhere for quite a while.
