when setting a div container's top position Firefox doesn't render the flash contained in the div until the scroll bar is rolled over. It sets the HTML position but doesn't render until you roll over the browser scroll bar. This is a very uncommon bug but is necessary to use flash elements with a height greater then 4000px. here is the implementation of the process http://www.kontain.com/fi/entries/684/the-flash-height-problem-and-how-to-solve-it/#entries/entry/684

Reproducible: Always

Steps to Reproduce:
1.scroll down the example link with a mouse wheel until the flash dissapears
2.roll over the scrollbar 
3.
Actual Results:  
scroll down the example link with a mouse wheel until the flash dissapears
roll over the scrollbar 

Expected Results:  
the flash should render

Please note im not trying to rip off the kontain site they just have a live version of the problem im having.

Sorry, can you explain step 2; do you mean scroll up?
And how far should I scroll down? I see also small flash objects on the right side. I see some gray flash. Is that what you mean?

just keep scrolling down (with the mouse wheel) until you get to the bottom or the flash disappears. if you get to the bottom without any result then try going slower. i know its a bit vague but once you see it you will know what i mean. basically when you scroll near to the bottom of the flash (max - 4000px) some javascript shifts the flash down by setting the top position it moves a few times before you get the render issue. this only happens on really large pages (ie a few shifts). if you dont understand try reading this link http://www.kontain.com/fi/entries/684/the-flash-height-problem-and-how-to-solve-it/#entries/entry/684
let me know if you need any more input.
thanks

Yes, ok, I see it now. I see it in all Firefox versions old and new, and also in Opera. So at least it is not a regression. It seems that it fails to redraw, especially while holding the scrollbar.

Sorry, now I re-read this bug I believe I still don't understand it. I see several weird things, e.g. while scrolling the flash on top initially appearing on a spot where it doesn't belong, but I think that's not what you mean and someone else should retest it.

I'm not entirely sure what u mean it could be a bug in their JavaScript but the bug I'm referring to is just the rendering bug.

We're in the process of removing support for plugins (bug 1677160), so I think this bug is irrelevant now.
