Haven't seen these for a long while, but the url http://people.netscape.com/rginda/warpcore/warpcam.html exhibits them: horizontal lines across the image which disappear after the window is obscured and revealed. The page uses 'width=100%'; my window is sized at 1206x932. Will attach a partial screenshot. Occurs about 40% of the time on my 56.6K line (I think that line speed is a major factor). This is with trunk as of writing.
Removing 'are back' from the summary since I think that implies that this is a recent regression which isn't necessarily the case.
Is this a duplicate of bug 83289?
Don't know. This bug has nothing to do with scrolling; the problem is visible while just sitting looking at the page load. Secondly, that bug is marked FIXED and my eyes say that this bug isn't.
Still seeing this intermittantly on this test case.
(with trunk build)
Is bug 190881 related to this?
Not unlikely... the symptoms sound the same.
The testcase on netscape.com no longer exists -> incomplete.
