[Tracking Requested - why for this release]:

When I scroll a long page that's fully loaded, I get a white screen that can last up to 10 seconds on my macbook air with servo enabled. 

https://www.w3.org/TR/html5/single-page.html

Looks like a bad painting issue
I have the same issue. About:support

Effective Content Process Sandbox Level: 3
I have tried this with Servo turned off (as seen in comment 2) and the painting and caching of the painting looks a lot better on larger documents.
I see this with and without stylo, and is also reproducible on Facebook if you scroll the feed to get a lot of content loaded and then try to scroll back. I compared to Chrome as well, which feels like it limits scroll speed (using mbp trackpad) but you don't see any blanking either.
I see this too. Recent regression--build from 9/10 didn't have it. Matt: can you help track this down? Thx.

Can someone that can repro please run mozregression [1] for this testcase?

I'm not seeing this in today's build. I do get the typical checkerboarding we get with APZ on fast-scrolling the HTML5 spec, but it's not the same as before (checkerboarding + scroll position not updating.)

Does this still occur for you? That is, do you still see 10 seconds of blank screen after you stop scrolling?

I'm still seeing the checkerboarding when scrolling quickly too, but it pops back once you stop. There's a bit of lag on the scroll position when you get going quickly, it hitches a bit, which isn't a nice visual (scroll position hitching + checkerboarding at the same time). 

0 checkerboarding would be nice, but I suspect that's oos here ;)

This appears to work for me now.
