Site is slow to load and I do see some black screen, after it is loaded, the content is not lost when scrolling.
Setting e10s flag.

Jim, what's the current situation with Flash and e10s/apz? I see bug 1229429 is still open, so I'm assuming they're not very high priority?

We hide plugin windows during scroll operations.

On Nightly you'll see content background because the sandbox prevents window plugin capture. That's currently being worked on in bug 1252877.
