Status: RESOLVED DUPLICATE of bug 524468

(Firefox :: Shell Integration, defect)

Description

[Zhang Yi Jiang]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2b2) Gecko/20091108 Firefox/3.6b2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2b2) Gecko/20091108 Firefox/3.6b2

All program/tab previews that appears when their icons are hovered over in Windows 7 are anti-aliased or processed/filtered in some way such that they appear smooth after resizing; this appears to be missing in both Firefox 3.6b2 and the latest Minefield build. The overall visual difference between Firefox previews and that of other programs is jarring and highly noticable.

Reproducible: Always

Steps to Reproduce:
1. Open up a session with multiple tabs
2. Hover over the Firefox icon in the taskbar

Actual Results:  
The tab previews are aliased, and the outline of objects in the preview jagged.

Expected Results:  
Tab previews should be anti-aliased and smoothed such that they are consistent with all other previews.
