This is a very odd bug in Firefox, which has been fixed in the development version, but not in the current distribution version (1.0.4).

If you have a div with the property "overflow: auto" inside a floated div, then when you resize the screen or cause Firefox to repaint the screen the overflowed element will flicker for an instant out of place. It seems that this only happens if the page is IN THE FIRST BROWSER TAB, on second, third etc. tabs there is no problem.

I don't know if anyone knows a workaround for this problem.


The only workaround I know of (which sometimes does work, sometimes not) is to absolutely position the overflowed element, or, if there is any bug trigger like a navigation outside of the overflowed element, to absolutely position that navigation/link. This is of course not always possible, because normally the layout relies on the floating, and often the designer does not want to change it.

In addition to the trigger you have mentioned, sometimes just text zooming cntrl +/- does show the problem. The first tab problem is new to me, nice catch.

You may have seen that the flickering content appears at a position where the div/object would have been placed without any margin or offset. That means, at the origin of its containing block. That's the idea behind the a.p. workaround.

You might want to share the URL to your testcase, so we could try to find more fixes.
