Status: RESOLVED DUPLICATE of bug 325296

(Firefox :: General, defect)

Description

[Erin Staniland]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/412.6 (KHTML, like Gecko) Safari/412.2
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-GB; rv:1.7.10) Gecko/20050717 Firefox/1.0.6

In the page at http://www.withassociates.com/firefox/ there is an element in the html page with it's 
opacity set to 0.5 with CSS.  This causes all text elements on the page to render incorrectly.  If you 
compare the text on this page to http://www.withassociates.com/firefox/normal.html you can see that on 
the first page the text isn't as bright, maybe more transparent.
I have tested this on Windows PC and there is no problem.

Reproducible: Always

Reproduced on Mac OS X 10.4.6:
Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1a2) Gecko/20060518 BonEcho/2.0a2 ID:2006051811

To reproduce: View test case page and normal page side-by-side.

Expected result: The text with opacity:1.0 should look the same on both pages.

Actual result: The text with opacity:1.0 in the test case is darker / has lower opacity.
