@jjeffryes are you able to reproduce this issue?

I can reproduce it.

It seems to happen if you scroll to the bottom, then quickly scroll up and back down. When you pull back down, instead of the content a blank background is shown in the scrolled down area (that was pulled from off the screen). It goes back to normal if you scroll back up and down again more slowly.

It's not a critical bug, if we can't find an obvious cause I think it's OK to leave this in production.
