Status: VERIFIED DUPLICATE of bug 543065

(Core :: XUL, defect)

Description

[u88484]

Menus shift a few pixels after a sub-menu is opened and selection switches to sub-menu.

STR:
1) Open bookmarks menu
2) Hover over the bookmarks toolbar (or a folder that has a sub-folder)
3) Move mouse to newly opened menu and watch the bookmark menu content shift to the left a few pixels.

Can also reproduce with View->Toolbars

I also see this problem.  On my system, it happens on both Vista and Windows 7, but not on XP.

looks like cset:
http://hg.mozilla.org/mozilla-central/rev/5dca6c28cca5 is ok
and
http://hg.mozilla.org/mozilla-central/rev/cea14ad20b61 is bad.

Which could only be two bugs. A patch from moving scrolling from the viewport to layout bug 526394 or the followup fix for the second bug 501095.

As bug states this also happens for Shredder. So its probably a widget issue.

I've made a case for a probably related issue where bookmarks jump off the toolbar: 

STR:

- Open latest Minefield with the attached profile
- Note the order of the Personal Toolbar, first you see "Most Visited" and then "Getting Started"
- Click on "New Folder" (on the right) and hover over the sub-folder "New Folder2"
- Note that at this point the first item "Most Visited" jumps to an invisible place on the left, and that the submenu opens on the newly allocated spot, leaving a gap between the menus.

This regressed with http://hg.mozilla.org/mozilla-central/rev/47cd92d616d7

So it's bug 526394.

Just wanted to note that this occurs not only on Windows platforms, but it also occurs on Mac OSX 10.6.2. I'm not certain about Linux builds, but the platforms certainly needs to be extended to Windows and Mac OSX.

If bug 526394 is correct, are there also CSS rules defining spacing/padding/borders on the menu widgets throwing them off?
