There appears to be a Windows GDI leak from the 2004-11-06-06 builds onward. 3.371 roc+%cs.cmu.edu 2004-11-05 05:59 Bug 243726. Fix up child-covering calculations. r+sr=bzbarsky is suspect. Steps to Reproduce: 1. Go to http://home.netscape.com 2. Click on the "What's New" tab at the top of the page. Expected Results: Using JavaScript/DOM, the window comes downward, with no black trails. Actual Results: The window that appears leaves a trail of black lines.

I very much doubt this is a GDI leak... probably an invalidation bug, almost certainly the same one as bug 268090.
Depends on: 268090

I can reproduce this with both GTK1 (mozilla.org nightly) and GTK2 (albeit with the recursive widget painting removed) builds... It looks like we're just not invalidating that area properly for some reason. The tentative patch in bug 268090 fixes this for me on Linux (GTK1), but that causes lots of double-painting in GTK1, so I'm not sure it fixes the real problem here, whatever that is...

Related, probably (since it appears with the same 11-06 build and disappears with the 11-05 build) is that under the "News" section on Netscape.com, we don't paint the underline on :hover, but we do with a click.
