Steps to reproduce:
1. Visit gmail.com
2. Note that the navigation links are no longer underlined

WORKS: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9b5pre) Gecko/2008032605 Minefield/3.0b5pre
FAILS: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9pre) Gecko/2008032705 Minefield/3.0pre

This seems to be Windows 2000 only.

Also tried with a fresh profile with no luck.

Comment 2

The links are underlined if I zoom out 2 steps.

I don't think we care about Windows 2000, but a reduced testcase could be nice.

Attachment: Testcase

Underlined span element inside a div element with overflow-y set to hidden.

This happens also on Windows XP.

Bug 425488 looks related. Same regression range.

[José Jeria]

OK, now I am really confused. I don't see this issue anymore. Haven't updated, still on 2008032705...

I can confirm this with today's nightly: 
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008032805 Minefield/3.0pre

Oddly, the test case WFM a minute ago. I restarted with a clean profile to try the new nightly, then got back to this profile and the testcase doesn't work for some zoom in and out levels.

Comment 9

[José Jeria]

Yes, this is very odd. It can happen for hours to then not be reproducible again for a couple of restarts.

Looks like this is a reoccurence of Bug 162818.  That testcase looks similar and is missing an underline.

There are two bugs, one is bug 162818, and I broke the underline position at bug 425249. I'll post a simple patch to bug 245488. This is simple mistake, sorry.
