I'm surprised that I couldn't find an exisiting bug for this one. I probably just missed it. Anyway, if you resize the window while viewing www.mozilla.org, the tables do not resize correctly, and instead leave a blank area between the link list on the left, and the middle area box (with the news in it.)
Works fine for me on NT with latest build. Re-assigning to Kevin to see if the problem is Linux specific (we seem to have a lot of Linux specific problems lately)
Ah ha! Far more tricky than I thought it was... This bug is only triggered when the page incrementally reflows a couple of times during page load. That's why hitting reload fixed it. When I turned off the memory cache, forceing it to pull the page through the modem again, and hit reload, the bug reappeared. Also, now that I look at it, the page renders incorrectly to begin with. (The window resize just makes it look worse) It renders correctly if it only lays-out once (as it does when it is in the cache.) I think you'll have to have a low speed connection to see it happen. For the record, I see it reflow three times while it loads. CCign back to firstname.lastname@example.org, since this information might be useful.
Tried with todays build and I was not able to reproduce the problem. This bug was probably fixed along with some general update issues on Linux. Marking as worksforme.
Resizes beautifully on Linux in build 2000060508
