We're looking into this... it's the QuickTime plug-in that is
flickering when scrolling. I looked at it on 10.4.6 on a PPC
machine and 10.4.7 on an Intel machine and only saw the flickering
on 10.4.7. Thanks for bringing it to our attention. (Note that
Flash already has flickering problems when scrolling with Flash 8
because of a rendering mode they use only with Safari. I believe
someone said Flash 9 might fix that issue.)
Actually, although that page was an easy one to reproduce a flicker,
I have seen a more widespread flicker on a few pages that don't seem
to have any plug-in based content. Since It happens so rarely, I
didn't provide an example before. However since one such page did it
for me again today I'll elaborate:
I have a tabbed folder on my Safari bookmarks bar that contains the
following URLs in this order:
http://www.macintouch.com/
http://www.versiontracker.com/macosx/index.shtml
http://www.macnn.com/
http://www.thinksecret.com/
http://www.macosrumors.com/
http://www.macoszone.com/
When I click on that folder, all the pages start to open with
MacinTouch being in the front tab.
Once in a while (maybe the first time every day?) Macintouch will
draw and totally white-out several times in quick succession until it
finally ends up with the finished content.
I imagine that this is partly due to images/css or other media coming
in at different times that forces a redraw, but I don't remember it
ever whiting out between redraws before 10.4.7.
(This tabbed folder has usually been the first thing I click on when
launching Safari, so I am sure I would have noticed it in an earlier OS)
Doing it again just now, I see that although Macintouch redraws a
couple of times while loading, there is no white-out between them.
Emptying the cache didn't help in reproducing it either.
