340484 - -moz-appearance: menupopup; leaves a ButtonFace color behind on hover

Status: RESOLVED DUPLICATE of bug 340517

(Core :: Graphics, defect)

Description

[Ria Klaassen (not reading all bugmail)]

This morning when I opened a new build of Firefox I was surprised by my different looking menu-items. When I opened the bookmarks-menu a very ugly hover trail in the color ButtonFace was left behind. When I moved my mouse outside the popup, the original white color came back.
I'll attach a screenshot.

It turned out to be the line -moz-appearance: menupopup; in my theme.
It happens only in Cairo and the behaviour changed only some hours ago: between 1.9a1_2006060515 and 1.9a1_2006060521.

Steps to reproduce:
- Put this in userChrome.css:

menupopup,
popup {
  -moz-appearance: menupopup !important;
}
 
- Open a Firefox menu and hover over the items.


If this is WONTFIX I would not have an objection because I did not know what to do with these findings anyway :(

Nope, definitely not WONTFIX; this was caused by some native theme breakage that I'm trying to track down.  Same bug as 340517, though.
