From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.14 i686; en-US; m14) BuildID: 2000033008 When I'm leaving a page with lots of list boxes, like bugzilla's Query page, the list boxes often spend a lot of time flickering and not allowing the browser to leave the page until they're done. On the Query page, the list boxes turn black, and appear to each individually redraw themselves with zero width (only the scrollbar is left), causing the list boxes after it on the page to redraw as well, and then redraw again at their normal width. Reproducible: Sometimes Steps to Reproduce: 1. Go to http://bugzilla.mozilla.org/query.cgi 2. Make a query and submit it. 3. Watch the list boxes jump around. Actual Results: The listboxes redraw themselves several times. The result is a mess of blackness and misplaced scrollbars that spend about 10 seconds jumping around before Mozilla can get on with things. Expected Results: The listboxes should have quietly disappeared like the rest of the page does.

This appears to no longer happen in current builds; the query page blanks out without redrawing the listboxes down to nothing (as far as I can see) and does so promptly as I leave. To check for rendering issues involving a slow X server, I artificially slowed down my X rendering (I ran Mozilla remotely displaying X over a ssh tunnel over a 28.8 PPP link, which is slow enough to show any rendering glitches); there was no problem in moving away from the page. (Visible form boxes repainted themselves black before the whole page went black and blanked, but that was quite fast, and they didn't reposition themselves.) I'm marking this WORKSFORME. Reporter, please reopen if this still happens for you with a current nightly build; you might want to include details about your X server environment.
