871227 - New tab mangles the graphical interface (and general rendering)

Status: RESOLVED DUPLICATE of bug 837489

(Firefox :: Untriaged, defect)

Description

[rowan.clemerson]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130409194949

Steps to reproduce:

When I add a new tab in Firefox (20.0.1), the graphical user interface (particularly around the search bar) often re-renders poorly. This results in the desktop background "peaking through". In a few cases the problem extends into webpages being displayed.

System: Windows 7 Pro, 64 bit (using Windows 'Aero')
GPU: Radeon 7850
Screen: Dell U2713HM (uses Dell Display Manager)

Notable Firefox addons: NASA Night Launch 0.6.20130409
Night Launch Companion 0.1.20130209.2142beta


Actual results:

A simple, but annoying, remedy is to make Firefox rerender itself, either through moving the window or resizing (through double tapping F11). However this doesn't stop the problem from manifesting again.

For a more permanent solution I tried disabling NASA Night Launch and it's affiliated addons; however, the problem persisted with 'Vanilla' Firefox display.

Disabling 'Desktop composition' in the Windows properties was also fruitless

As far as I can tell, there is nothing wrong with my graphics setup (i.e. the gaphics card is fine, as is the screen).


Expected results:

I would like to open new tabs without Firefox rendering poorly.
