If you have a page that contains an iframe whichs height style is bigger then
16384px all the 'pixels' over 16384 don't get rendered (if you move a window
overthem there is visual corruption...no repainting.

If the iframe contains a page(a page bugger than 16384px), the iframe behaves as
if it was only 16384 pixel in height and it's scrollbars work accordingly, but
the pixels >16384px never get repainted.

Easy repro create a file with the contents below. le last 10 pixels will never
repaint if you move a window(or minimize, maximize firefox) over the iframe.
If you want a more drastic effect set the height to something big like 17684px.
----------------------------------
<html>
	<head>
	</head>
	<body>
		Here1
		<iframe src="" style="width:600px;height:16394px"></iframe>
		Here2
	</body>
</html>


Reproducible: Always

Steps to Reproduce:
1. Create a t.html file containing the code detailed in the details.
2. Open it with FireFox
3. Minimize and maximize firefox, the last 10 pixels will not have been repainted.
Or move a window over the last pixels, same problem.

Actual Results:  
Corruption in the last 10 pixels of the iframe.

Expected Results:  
Painted the region accordingly. If a big document is used as source, the
scrollbar should use the extra (>16384px) pixels to display the document.
CAn you please attach a testcase showing this issue or retest with the latest alpha?

This is the file that contains the offending iframe. Juste scroll to the bottom
(with the browsers scrollbar not the iframes) minimize the browser window and
then maximize it. the bottom of the frame will be corrupted.
Juste a many line file included in the iframe (the src attribute) so we can see
the problem.
The problem doesn't occur in the release you told me to test on (deer-park-
alpha-2-released). thanks
This has been fixed after 1.0.6 (using a gecko engine older than one year) then.
