i see no flicer in the URL here, nor in the testcase, using 2002040903 XP. i see severe flicker in bug 136549 though - perhaps another bug.

forget comment 1 - i DO see flicer! Comment was intended for another bug.

may be related to bug 136549 (and, originally, bug 128133) Jake

jkeiser, does your overflow-and-scrolling-stuff patch fix this?

Changing QA contact

I see it still in Linux 2002041407, which landed after bug 119849. It is entirely possible that there is a similar problem here. I fixed one instance of the problem in that bug, but not all. If anyone calls nsBoxToBlockAdaptor::GetPrefSize(), for example, the unconstrained reflow will happen again.

maybe related to bug 96756, because position:relative; fixes the flickering problem...

Is this still a problem?

If bug 136549 is related to this, then yes, it is still a problem. See the most recently posted minimized testcase in that bug. There is a slight flicker at the top of the screen early on when using the menus. It doesn't persist, but it shouldn't be there at all. Jake

Bug 136549 is bug 136549. What does that have to do with this bug? Unless you're saying this should be marked duplicate?

If you don't think that bug 136549 has anything to do with this bug (duplicate or whatever), then ignore my comment. I just thought it might be related. If the same problem is causing the issue in that bug as this and it is apparent that the testcase in that bug still displays the problem, then this bug is still an issue. It was just a hunch. I have not looked at the Mozilla code that might be causing the issue as you probably have, so I defer to your wisdom. Jake

Well, it's just a matter of: 1) If the only testcase that demonstrates this bug is in bug 136549 then this is a duplicate. 2) If the testcase in bug 136549 has nothing to do with this bug, then this is worksforme. Randomly picking a resolution....

hi! <<If the only testcase that demonstrates this bug is in bug 136549 then this is a duplicate.>> # you can see a severe flickering on http://www.bierdatenbank.de/testDir/biertests_standard.htm, whether its related do bug 136549, or not... cheers seth

sorry, i was unfortunately using an wrong (older) version of mozilla. in 1.3 there is no flickering on that example-page. again: i'm very sorry for that mistake! cheers seth

Boris, I just rechecked the testcase in bug 136549 with the latest Mozilla Firebird and I see no flicker. I resolved that as WFM. Your random resolution is probably correct here as well. Mozilla is behaving quite nicely :-) Jake
