852168 - Incorrect display of web-sites

Status: RESOLVED DUPLICATE of bug 812695

(Firefox :: Untriaged, defect)

Description

[8145678]

Attachment: Screenshot_firefox_20.0_a.pdf

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130313170052

Steps to reproduce:

Up to now I was very satisfied using firefox and recommended it to all my companions and colleagues. Since a few days/weeks I must complain the following:
Please have a look at the attached screenshot (a) when using firefox 20.0:
The shown incorrect display sometimes disappears in about 3-5 seconds and changes to proper display without me having done nothing. But also sometimes remains incorrect. If I move the cursor over the relevant passages with pressed left mouse-button the text becomes normal and clear!  But the moment I scroll the page even only a bit up or down an incorrect display is back again.


Actual results:

Incorrect display of text (see two attachments):
First I supposed this to be a defect of my flat-screen or my graphics-card.
But this is not the reason:
The Defect does not show when using Microsoft Internetexplorer 10 or Chrome!!!



Expected results:

Are you aware of this defect? Is this just a temporary 'mis-behaviour' of firefox version 20.0 (beta)?
Best regrads,

Does it work if you disable the hardware acceleration ?
(tools/advanced/general followed by a restart)

Please post the graphic section of about:support if that fixes it.
