Hello,

Confirmed as well. And hopefully understood. I think the problem is that visibility testing is not performed if the scroll bar does not change, hence a lot of invisible pages get rendered and the rendering results are never discarded or cached. (It get's worse if you scroll faster. Try just holding down space. :-))

I will hopefully be able change that now but I think this will seriously reduce prefetching effectiveness which will hence have to go through the page cache again... Well I never liked prefetching anyway... :-\

Best regards, Adam.
