Able to reproduce this on the latest M-53(53.0.2769.0) on Mac OS, Linux Ubuntu 14.04 and on Windows-7(53.0.2768.0). Issue is seen from older chrome version: 30.0.1549.0 as tested on Windows-7.

On Firefox I am seeing black pages when scrolling directly to the bottom of the page.

Marking this as Untriaged for further investigating.

It is like the rendering is stopping there too. Must be some limit inside the paint algorithm and we are hitting that for hit testing too.

LayoutUnits can go up to twice that (INT_MAX / 64) but perhaps I'm missing some factor of 2.

There's been some long debate about whether we should support outsized pages like this. I'm not sure what limit we're hitting here but I'm not sure it's worth the effort to fix. +danakj@,aelias@ who've had opinions here in the past.

I believe there's a size limit in GraphicsLayer. Not sure why we'd be able to scroll past that though.
