907756 - Scolling bug 871445 to the bottom changes the background

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Mounir Lamouri (:mounir)]

With the new Bugzilla theme, when a bug is very long (like bug 871445), scrolling to the bottom changes the background to something a bit darker (more brown). I have been able to reproduce this on Firefox 22 and a relatively recent tree (a week).

Simon was able to reproduce this but not someone else at the office so it might be a Linux-only problem.

BTW, simply STR:
1. Open https://bugzilla.mozilla.org/show_bug.cgi?id=871445
2. Notice the background colour
3. Press the "End" key to go at the bottom of the page
4. Notice the background colour

Expected result: steps 2 and 4 have the same background colour.

Actual result: steps 2 and 4 do not have the same background colour.

Also, if you scroll you will see glitches that show that it is unlikely a CSS problem.

Confirmed if HWA turned off.

Has this been seen on non-Windows platform, or can we change the platform field above?
