655447 - sub-menus (bookmarks, etc) stutter when using dual screens.

Status: UNCONFIRMED

(Firefox :: Menus, defect)

Description

[Zoughtbaj]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1

I am currently running a two screen setup, and when I move the firefox application to the other screen and try to use any of the sub-menus, such as the bookmarks tab, the menus stutter to the point of not being able to use them.

Reproducible: Always

Steps to Reproduce:
1. set-up a dual screen system.
2. open the firefox application. Move it to the secondary screen.
3. click on any of the menu tabs, such as the firefox, most visited, or bookmarks tab
4. There should be s stuttering in the menus when the pointer is moved across it.

Actual Results:  
The menus stutter.

Expected Results:  
They should be staying solid, as they do in the primary screen.

 My screens are different resolutions, however, I have tried changing the secondary screen's resolution and making the primary screen's resolution equal to the secondary, but the problem stays the same, so I think the difference is a non-issue.

Does disabling the h/w acceleration inside the advanced pane of the preferences help? Have you seen that in Firefox 3.6?
