Scrolling with repaint flash on shows the whole web view repaints when scrolling
with 20050506. 0.8.4 only repaints new areas.
20050219 paints correctly
20050220 paints everything
The nightlies only repaint what's scrolled into view for me...*unless* there's
an animated element on the page. I think this is a dupe of another bug.
I see this on all pages. OS 10.4
-> simon for duping or triage.

I can't reproduce this on 10.3.  Downloaded the two mentioned Camino nightlies.
 Loaded www.mozilla.org on both.  Enabled "Flash screen update (yellow)" in
Quartz Debug, and then used the arrow keys to scroll up and down.  Only
repainted areas that came into focus.  Same thing when I used the scrollbar to
go up and down.

Maybe 10.4 only?  I'll have to test at home tonight.
Strange.  Just tested on 10.4, and both nightlies draw the full page on scroll,
whereas on 10.3 they only drew the changed area.
*Sigh.* Tiger vs. QuickDraw thing?
Hmm, I see full page redraw on Firefox for those two dates, also.  Just to make
sure, I also started up Safari and scrolled mozilla.org on that browser and saw
the same thing.  Maybe this is a new 10.4 thing?
10.4 has some changes to the way the cocoa updates windows. This probably also
causes the occasional rendering issues in Camino.

2005-02-19 does not have full page repaints on 10.4 at mozilla.org for me. Make
sure to test in a new window because of bug 249518.


Did anyone ever determine whether this was a regression for sure or not?  This
might be part of the problem in bug 299569 perhaps?

Is this fixable for 1.0?  It's a regression that's currently untargeted.
I don't think we can easily fix this, and I don't see it being a serious problem.

I can't repro this anymore.  Anyone else?
