21685 - Vertical Lines at certain browser widths

Status: VERIFIED DUPLICATE of bug 5251

(Core :: Layout: Tables, defect, P3)

Description

[Brad Fitzpatrick]

When resizing Mozilla to certain widths, black, single-pixel wide vertical lines
appear beside tables and images.

For example, try going to Slashdot and resizing the window to 710 pixel wide by
any height.  There will be black line beside the Slashboxes, and a black line
between the 1st and 2nd topic icons at top.

If this example doesn't work for you (if, for example, Slashdot's image widths
for the topics change and render this example invalid), just resize the window a
bunch until they appear.  A screenshot will be attached shortly.

I forgot to mention--- turn off the sidebar before trying to see this bug.  (the
presence of the sidebar or not doesn't affect the bug from happening, but it
makes the 710 wide window example work....)

More notes... this was using Mozilla build 1999121308

Yeah, I see the black lines, too. Appears to be table related

I'm still seeing this bug in build 2000122320, a year now from when I first 
reported it.
