467832 - Black line appears on Google Groups message when I zoom out 1x

Status: RESOLVED DUPLICATE of bug 468496

(Core :: Layout, defect)

Description

[Daniel Holbert [:dholbert]]

Steps to reproduce:
 1. Load URL (or any Google Groups conversation)
 2. Zoom out 1x, with "ctrl minus"

ACTUAL RESULTS:
 - There's a black line on the left edge of each "bubble" in the conversation.
 - The "Recently Visited Groups" dropdown button (in upper-right corner) has its bottom edge cut off

Related issue: if I zoom *in* 1x or 3x from the default zoomlevel, I get similar weird black lines at the left corners of the subject bar (i.e. to the left of "Firefox / Gecko Delivery meeting" in this case)

related to bug 477552?

I guess so they have the same regression range.

bug 477552 is now marked a duplicate of bug 468496 and apparently that's not a
transitive property.
