866319 - Odd pixel color in lettering

Status: RESOLVED DUPLICATE of bug 812695

(Firefox :: Untriaged, defect)

Description

[woodeee]

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

Steps to reproduce:

Only in Firefox - looking closely at lettering in text messages the colors of pixels show as red, green and blue - not black, giving a blurred effect. Coloring is normal for a few seconds and then defect appears. 

Restart without addons no different. Reverted back to FF19 - still the same. Uninstalled and reloaded FF20 still the same. 

Indications normal in IE10 and Slimbrowser.

Highlighting text reverts letters to black.

Thanks for your response -  

I now find it randomly appears in a sentence then corrects itself within a few seconds.

I will continue to monitor and advise accordingly.

Not sure how to send an attachment, have copied an example to a Word page, if I highlight to copy it the coloring disappears.

Take a print screen (keyboard) and save it as jpeg or png, then attach it to this bug:

Also carried out a pixel fault scan of my 4 year old AOC monitor - no faulty pixels evident.

Just uninstall the MS update KB2670838 to fix it.
